Il est déjà connu de constituer un commutateur double en disposant dans un même module, l'interrupteur auxiliaire et l'interrupteur de signalisation pour indiquer à la fois l'état fermé ou ouvert des contacts, et la nature de l'ouverture du disjoncteur avec ou sans défaut. Le mécanisme commun d'actionnement des deux interrupteurs est compliqué, car il nécessite généralement une rupture de la liaison mécanique avec l'interrupteur de signalisation lors d'une ouverture manuelle du disjoncteur. De tels mécanismes sont décrits dans les documents EP-A-147.605, DE-A-3.119-165 et DE-A-3.320.958. Dans un disjoncteur automatique modulaire, l'adjonction d'autres auxiliaires électriques pose un problème de transmission de l'ordre de déclenchement entre le bloc disjoncteur et les différentes auxiliaires accolés.It is already known to constitute a double switch by having in the same module, the auxiliary switch and the signaling switch to indicate both the closed or open state of the contacts, and the nature of the opening of the circuit breaker with or flawless. The common mechanism for actuating the two switches is complicated, since it generally requires the mechanical connection with the signaling switch to be broken when the circuit breaker is opened manually. Such mechanisms are described in documents EP-A-147,605, DE-A-3,119-165 and DE-A-3,320,958. In a modular automatic circuit breaker, the addition of other electrical auxiliaries poses a problem of transmission of the tripping order between the circuit breaker block and the various adjoining auxiliaries.

L'objet de l'invention consiste à perfectionner le mécanisme d'actionnement d'un commutateur auxiliaire double pour permettre l'adjonction d'une pluralité d'auxiliaires à un bloc disjoncteur.The object of the invention is to improve the actuation mechanism of a double auxiliary switch to allow the addition of a plurality of auxiliaries to a circuit breaker block.

Le commutateur selon l'invention est caractérisé en ce que le premier interrupteur auxiliaire comporte un bras de contact coopérant directement avec la platine associée à un ressort accumulateur d'énergie, et que le bras de contact du deuxième interrupteur de signalisation est portée par un levier support isolant monté à rotation limitée sur l'axe de la platine, ledit levier support ayant une saillie susceptible de coopérer avec un levier de commande pivotant sur l'axe de la manette de manière à interdire tout déplacement du levier support par blocage de la saillie lors d'une ouverture manuelle sans défaut du disjoncteur laissant le deuxième interrupteur dans un état inactif, et à autoriser le pivotement du levier support pour la commutation du deuxième interrupteur vers l'état actif de signalisation de défaut lors de la rupture de l'accrochage intervenant suite à un déclenchement automatique du disjoncteur.The switch according to the invention is characterized in that the first auxiliary switch comprises a contact arm cooperating directly with the plate associated with an energy storage spring, and that the contact arm of the second signaling switch is carried by a lever insulating support mounted with limited rotation on the axis of the plate, said support lever having a projection capable of cooperating with a control lever pivoting on the axis of the handle so as to prevent any movement of the support lever by blocking the protrusion during a faultless manual opening of the circuit breaker leaving the second switch in an inactive state, and authorizing the pivoting of the support lever for switching the second switch to the active fault signaling state when the latching occurring following an automatic tripping of the circuit breaker.

Le levier de commande est doté d'un secteur circulaire de guidage se déplaçant avec la manette le long de la saillie lorsque le levier support est immobilisé en rotation au cours de l'ouverture manuelle du disjoncteur.The control lever is provided with a circular guide sector which moves with the lever along the projection when the support lever is immobilized in rotation during the manual opening of the circuit breaker.

L'ouverture sur défaut du disjoncteur est également signalé localement au moyen d'un voyant de signalisation agencé sur le levier support de manière à être visible depuis la face antérieure du boîtier. Le voyant de signalisation de défaut comporte un organe de réarmement manuel du levier support autorisant le passage du bras de contact appartenant au deuxième interrupteur de signalisation de l'état actif vers l'état inactif.The opening on fault of the circuit breaker is also signaled locally by means of a signaling light arranged on the support lever so as to be visible from the front face of the box. The fault signaling indicator comprises a manual reset member of the support lever authorizing the passage of the contact arm belonging to the second signaling switch from the active state to the inactive state.

Sur la figure 1, un disjoncteur automatique 10 multipolaire est formé par l'assemblage modulaire d'un bloc auxiliaire 14 de commande et de signalisation à un bloc disjoncteur 11 ayant une pluralité de pôles 12 de coupure juxtaposés.In FIG. 1, a multipole automatic circuit breaker 10 is formed by the modular assembly of an auxiliary control and signaling unit 14 to a circuit breaker block 11 having a plurality of juxtaposed breaker poles 12.

Chaque pôle du disjoncteur 10 comporte une paire de contacts séparables pour l'interruption du circuit électrique ménagé entre deux bornes de connexion 13, 15, et un mécanisme de commutation associé à une manette 16 pivotante de commande manuelle, et à un déclencheur automatique destiné à surveiller la valeur du courant traversant le pôle. Le mécanisme de commutation d'un tel pôle de disjoncteur est décrit à titre d'exemple dans la demande de brevet français n° 8708037, déposée par la demanderesse le 9/6/87. Les manettes 16 des différents pôles 12 de coupure sont solidarisées mécaniquement entre elles par une barrette de couplage 18 en forme de traverse s'étendant dans la direction d'accolement des boîtiers isolants de logement des pôles 12. La présence de cette barrette 18 permet d'entraîner simultanément les manettes 16 des différents pôles 12 entre des positions stables de fermeture et d'ouverture du disjoncteur 10.Each pole of the circuit breaker 10 comprises a pair of separable contacts for interrupting the electrical circuit formed between two connection terminals 13, 15, and a switching mechanism associated with a pivoting lever 16 for manual control, and with an automatic trip device intended for monitor the value of the current flowing through the pole. The switching mechanism of such a circuit breaker pole is described by way of example in French patent application No. 8708037, filed by the applicant on 9/6/87. The levers 16 of the different cutoff poles 12 are mechanically secured to each other by a coupling bar 18 in the form of a crosspiece extending in the direction of abutment of the insulating housings for housing the poles 12. The presence of this bar 18 makes it possible to '' simultaneously driving the handles 16 of the different poles 12 between stable closing and opening positions of the circuit breaker 10.

Le bloc auxiliaire 14 est logé dans un boîtier 19 isolant (figures 2 à 5) renfermant un commutateur ayant une manette 20 pivotante sur un axe 21 et un mécanisme 22 d'actionnement combiné d'un interrupteur auxiliaire 24 et d'un interrupteur de signalisation 26. La manette 20 est accouplée à la barrette de couplage 18 des pôles 12 par une première liaison mécanique 28 (figure 1) bidirectionnelle permettant la transmission des mouvements de pivotement des manettes 16 du bloc disjoncteur 11 vers le mécanisme 22 du bloc auxiliaire 14. Cette liaison peut être réalisée à titre d'exemple par le prolongement de la barrette 18.The auxiliary unit 14 is housed in an insulating box 19 (FIGS. 2 to 5) containing a switch having a lever 20 pivoting on an axis 21 and a mechanism 22 for the combined actuation of an auxiliary switch 24 and a signaling switch 26. The lever 20 is coupled to the coupling bar 18 of the poles 12 by a first mechanical connection 28 (FIG. 1) bidirectional allowing the transmission of the pivoting movements of the levers 16 of the circuit breaker block 11 to the mechanism 22 of the auxiliary block 14. This connection can be produced by way of example by extending the bar 18.

Le premier interrupteur auxiliaire 24 comporte un système de contacts inverseurs ayant un bras de contact 30 mobile en forme d'épingle recourbée dont l'une des extrémités 32 est ancrée autour d'un bossage 34 du boîtier 19, et reliée électriquement à une borne 36 de raccordement. L'autre extrémité libre du bras de contact 30 porte un contact double 38 coopérant alternativement avec deux contacts fixes 40,42 distincts connectés électriquement à deux autres bornes 44,46 de raccordement. L'état de l'interrupteur auxiliaire 24 reflète la position ouvert ou fermé des contacts du bloc disjoncteur 11 auquel est accouplé le bloc auxiliaire 14 par la première liaison mécanique 28. Il en résulte des fonctions de commande et de signalisation grâce au premier jeu des trois bornes 36,46,44 isolées entre elles et superposées sur l'une des faces latérales étroites du boîtier 19. L'élasticité de l'épingle du bras de contact 30 assure la pression de contact sur les deux contacts fixes 40,42.The first auxiliary switch 24 comprises a reversing contact system having a movable contact arm 30 in the form of a bent pin, one of the ends 32 of which is anchored around a boss 34 of the housing 19, and electrically connected to a terminal 36 connection. The other free end of the contact arm 30 carries a double contact 38 cooperating alternately with two separate fixed contacts 40,42 electrically connected to two other connection terminals 44,46. The state of the auxiliary switch 24 reflects the open or closed position of the contacts of the circuit breaker block 11 to which the auxiliary block 14 is coupled by the first mechanical connection 28. This results in control and signaling functions thanks to the first set of three terminals 36,46,44 insulated from one another and superimposed on one of the narrow lateral faces of the housing 19. The elasticity of the pin of the contact arm 30 ensures the contact pressure on the two fixed contacts 40,42.

Le deuxième interrupteur de signalisation 26 comprend également un système de contacts inverseurs ayant un bras de contact 48 mobile à contact double 50 coopérant avec deux contacts fixes 52,54, l'ensemble de ces contacts 48,52,54 étant en liaison électrique avec un deuxième jeu de bornes 56,58,60 agencées sur l'autre face latérale étroite du boîtier 19, à l'opposé des bornes 36,46,44 du premier jeu. L'état du deuxième interrupteur 26 du bloc auxiliaire 14 permet de signaler l'ouverture sur défaut par déclenchement automatique du bloc disjoncteur 11.The second signaling switch 26 also includes a reversing contact system having a movable contact arm 48 with double contact 50 cooperating with two fixed contacts 52,54, all of these contacts 48,52,54 being in electrical connection with a second set of terminals 56, 58, 60 arranged on the other narrow side face of the housing 19, opposite the terminals 36, 46, 44 of the first set. The state of the second switch 26 of the auxiliary unit 14 makes it possible to signal opening on fault by automatic tripping of circuit breaker block 11.

Le mécanisme 22 d'actionnement du bloc auxiliaire 14 est composé d'une platine 62 mobile, en matériau isolant montée à pivotement limité sur un axe 64 fixe du boîtier 19. La platine 62 est reliée à la manette 20 par l'intermédiaire d'une biellette 66 de transmission et d'un accrochage 68 formé par un levier d'encliquetage 70 coopérant avec un levier de déclenchement 72. Le levier d'encliquetage 70 est monté à rotation sur un axe 74 de la platine 62, et est directement accouplé à la biellette 66. Le levier de déclenchement 72 du mécanisme 22 est monté à pivotement sur un axe 76 entre une position armée et une position déclenchée. Un ressort de rappel 78 du type à torsion est enfilé sur l'axe 76 et sollicite le levier de déclenchement vers la position armée (figure 2). L'une des extrémités du levier double de déclenchement 72 permet d'assurer l'établissement ou la rupture de l'accrochage 68 avec le levier d'encliquetage 70, et l'autre extrémité porte une tige 80 (figure 3) pouvant être actionnée par la barre de déclenchement incorporée dans le mécanisme de commutation du pôle 12 accolé. La tige 80 saillante traverse une ouverture 82 ménagée dans la grande face latérale 84 du boîtier 19 venant en engagement avec la face conjuguée du bloc disjoncteur 11. Lors de l'assemblage des deux blocs 11,14, la tige 80 pénètre dans un orifice du bloc disjoncteur 11 pour former une deuxième liaison de déclenchement (figure 1) entre le mécanisme de commutation du pôle 12 voisin et le mécanisme 22 d'actionnement du bloc auxiliaire 14. La présence de cette deuxième liaison 86 permet de dériver du mouvement de déclenchement intervenant dans l'un quelconque des mécanismes de commutation des pôles 12, un mouvement de pivotement vers la position déclenchée du levier de déclenchement 72 entraînant la rupture de l'accrochage 68.The mechanism 22 for actuating the auxiliary unit 14 is composed of a movable plate 62, of insulating material mounted with limited pivoting on a fixed axis 64 of the housing 19. The plate 62 is connected to the lever 20 by means of a connecting rod 66 for transmission and an attachment 68 formed by a latching lever 70 cooperating with a trigger lever 72. The latching lever 70 is rotatably mounted on an axis 74 of the plate 62, and is directly coupled to the link 66. The trigger lever 72 of the mechanism 22 is pivotally mounted on an axis 76 between an armed position and a triggered position. A return spring 78 of the torsion type is threaded on the axis 76 and biases the trigger lever towards the armed position (FIG. 2). One end of the double trigger lever 72 ensures the establishment or rupture of the coupling 68 with the latching lever 70, and the other end carries a rod 80 (FIG. 3) which can be actuated by the trigger bar incorporated in the switching mechanism of the pole 12 attached. The protruding rod 80 passes through an opening 82 formed in the large lateral face 84 of the housing 19 coming into engagement with the mating face of the circuit breaker block 11. During the assembly of the two blocks 11,14, the rod 80 penetrates into an orifice of the circuit breaker block 11 to form a second tripping link (Figure 1) between the switching mechanism of the neighboring pole 12 and the mechanism 22 for actuating the auxiliary block 14. The presence of this second link 86 makes it possible to derive from the intervening tripping movement in any one of the pole switching mechanisms 12, a pivoting movement towards the triggered position of the trigger lever 72 causing the coupling 68 to break.

A l'opposé de l'accrochage 68 par rapport à l'axe 64, la platine 62 porte un taquet 88 venant en engagement avec la partie intermédiaire du bras de contact 30 de l'interrupteur auxiliaire 24 en position de fermeture du bloc disjoncteur 11 (voir figure 2). Un ressort accumulateur 90 de traction est accroché entre le taquet 88 et un point fixe 92 du boîtier 19, de manière à provoquer le pivotement de la platine 62 dans le sens trigonométrique après rupture de l'accrochage 68 suite à un défaut. Le ressort accumulateur 90 sert de ressort d'actionnement du mécanisme 22.Opposite the attachment 68 relative to the axis 64, the plate 62 carries a cleat 88 which comes into engagement with the intermediate part of the contact arm 30 of the auxiliary switch 24 in the closed position of the circuit breaker block 11 (see figure 2). A traction accumulator spring 90 is hooked between the cleat 88 and a fixed point 92 of the housing 19, so as to cause the pivoting of the plate 62 in the trigonometric direction after breaking of the hooking 68 following a fault. The accumulator spring 90 serves as an actuating spring for the mechanism 22.

Sur l'axe 64 de la platine 62 est monté un levier support 94 ayant une première branche 96 inférieure servant de porte-contact au bras de contact 48 de l'interrupteur de signalisation 26, et une deuxième branche 98 opposée, équipée d'un voyant 100 de signalisation. Une butée 102 de la platine 62 prend appui sur le levier support 94 en position fermé du bloc disjoncteur 11 (figure 2), et assure un verrouillage positif du contact 50 du bras de contact 48 contre le contact fixe 52.On the axis 64 of the plate 62 is mounted a support lever 94 having a first lower branch 96 serving as a contact carrier for the contact arm 48 of the signaling switch 26, and a second opposite branch 98, equipped with a indicator light 100. A stop 102 of the plate 62 bears on the support lever 94 in the closed position of the circuit breaker block 11 (FIG. 2), and ensures positive locking of the contact 50 of the contact arm 48 against the fixed contact 52.

Le levier support 94 est doté d'une troisième branche latérale en forme de saillie 104 susceptible de coopérer avec un levier de commande 106 monté sur l'axe 21 de la manette 20. Un ressort de rappel 108 est associé au levier de commande 106, lequel est sollicité en direction de la saillie 104. Le levier 106 comporte de plus un secteur 110 circulaire de positionnement et de guidage de la saillie 104, et un bec 112 d'accrochage susceptible de coopérer avec un curseur 113 de verrouillage d'un sélecteur 114. Une entaille 116 ménagée dans la face supérieure du sélecteur 114 permet de déplacer le curseur 113 entre une position de verrouillage (voir figure 2) du levier de commande 106, lequel reste alors fixe lors du pivotement de la manette 20, et une position de déverrouillage autorisant l'entraînement du levier de commande 106 par la manette 20. L'entaille 116 du sélecteur 114 est accessible à travers une ouverture pratiquée dans la face antérieure du boîtier 19.The support lever 94 is provided with a third lateral branch in the form of a projection 104 capable of cooperating with a control lever 106 mounted on the axis 21 of the lever 20. A return spring 108 is associated with the control lever 106, which is biased towards the projection 104. The lever 106 further comprises a circular sector 110 for positioning and guiding the projection 104, and a hooking spout 112 capable of cooperating with a slider 113 for locking a selector 114. A notch 116 formed in the upper face of the selector 114 makes it possible to move the cursor 113 between a locking position (see FIG. 2) of the control lever 106, which then remains fixed when the lever 20 is pivoted, and a position unlocking allowing the control lever 106 to be driven by the lever 20. The notch 116 of the selector 114 is accessible through an opening made in the front face of the housing 19.

Un ressort de torsion 120, monté sur le levier support 94 autour de l'axe 64, coopère avec le bras de contact mobile 48 de l'interrupteur de signalisation pour exercer la pression de contact.A torsion spring 120, mounted on the support lever 94 around the axis 64, cooperates with the movable contact arm 48 of the signaling switch to exert the contact pressure.

Un gradin 118 du voyant 100 de signalisation permet l'annulation du signal défaut au moyen d'un outil destiné à repousser le levier support 94 vers la position de la figure 2.A step 118 of the indicator light 100 allows cancellation of the fault signal by means of a tool intended to push the support lever 94 towards the position of FIG. 2.

L'accrochage du bloc auxiliaire 14 sur le bloc disjoncteur 11 s'effectue au moyen d'un crochet 130 (figure 3) d'encliquetage faisant partie du boîtier 19.The auxiliary block 14 is hooked onto the circuit breaker block 11 by means of a snap hook 130 (FIG. 3) forming part of the housing 19.

Le fonctionnement du bloc auxiliaire 14 de commande et de signalisation est le suivant:The operation of the auxiliary control and signaling unit 14 is as follows:

DISJONCTEUR DANS L'ETAT FERMECIRCUIT BREAKER IN THE CLOSED STATE

En position de fermeture du disjoncteur 10, la manette 20 du bloc auxiliaire 14 se trouve à droite (voir figure 2), et le voyant de signalisation 100 est dans une position effacée. Les bras de contact 30,48 mobiles respectifs des premier et deuxième interrupteurs 24,26 sont maintenus en engagement contre les contacts fixes 40,52, et l'accrochage 68 est bien entendu en position verrouillée. Le ressort de traction 90 du mécanisme d'actionnement 22 est armé. Le sélecteur 114 est représenté dans la figure 2 en position verrouillée de blocage du levier de commande 106.In the closed position of the circuit breaker 10, the handle 20 of the auxiliary unit 14 is on the right (see FIG. 2), and the indicator light 100 is in a deleted position. The respective movable contact arms 30, 48 of the first and second switches 24, 26 are held in engagement against the fixed contacts 40, 52, and the latch 68 is of course in the locked position. The tension spring 90 of the actuating mechanism 22 is armed. The selector 114 is shown in FIG. 2 in the locked position for blocking the control lever 106.

OUVERTURE AUTOMATIQUE OU MANUELLE DU DISJONCTEUR AVEC DEVERROUILLAGE DU SELECTEUR.AUTOMATIC OR MANUAL OPENING OF THE CIRCUIT BREAKER WITH UNLOCKING THE SELECTOR.

Pour déverrouiller le sélecteur 114 à partir de sa position de verrouillage (figure 2), il suffit de passer un point dur formé par un bossage 122 coopérant avec une patte 124 élastique (figure 5) en repoussant le curseur 113 vers la droite, (voir flèche F1, figure 2). Le bec 112 d'accrochage du levier de commande 106 est alors libéré de l'action de blocage du curseur 113 autorisant l'entraînement du levier 106 par la manette 20.To unlock the selector 114 from its locking position (FIG. 2), it suffices to pass a hard point formed by a boss 122 cooperating with an elastic tab 124 (FIG. 5) by pushing the slider 113 to the right, (see arrow F1, figure 2). The spout 112 for hooking the control lever 106 is then released from the blocking action of the slider 113 allowing the lever 106 to be driven by the lever 20.

Lors d'une ouverture automatique du disjoncteur 10 sur défaut, la barre de déclenchement provoque le déclenchement du mécanisme de commutation du bloc disjoncteur 11, et transmet simultanément cet ordre de déclenchement (voir flèche F2 sur figure 3) vers le bloc auxiliaire 14 par la deuxième liaison mécanique 86, entraînant le pivotement du levier de déclenchement 72 dans le sens inverse des aiguilles d'une montre, vers la position déclenchée. Il en résulte une rupture de l'accrochage 68, suivie de la détente du ressort accumulateur 90 et du pivotement combiné de la platine 62 et du levier support 94 autorisant le changement de position des deux bras de contact 30,48 (figure 6). Le contact double 38,50 des deux interrupteurs 24,26 se trouve en engagement respectif avec les contacts fixes 42,54. Le premier interrupteur auxiliaire 24 indique le changement de position des contacts du bloc disjoncteur 11. Le passage à gauche de la manette 20 vers la position d'ouverture, assure le réarmement automatique de l'accrochage 68. Le deuxième interrupteur 26 de signalisation indique la nature de l'ouverture en reflètant le déclenchement du défaut du bloc disjoncteur 11. Ce défaut est signalé par l'apparition du voyant 100 sur la face avant du boîtier 19. L'annulation du signal défaut est opérée manuellement en repoussant le levier support 94 dans le sens des aiguilles d'une montre, au moyen d'un tournevis prenant appui sur le gradin 118.When the circuit breaker 10 opens automatically on fault, the trip bar triggers the switching mechanism of the circuit breaker block 11, and transmits simultaneously this tripping order (see arrow F2 in FIG. 3) to the auxiliary unit 14 by the second mechanical link 86, causing the tripping lever 72 to pivot in the anticlockwise direction, towards the tripped position. This results in a break in the coupling 68, followed by the relaxation of the accumulator spring 90 and the combined pivoting of the plate 62 and the support lever 94 allowing the position of the two contact arms 30,48 to be changed (FIG. 6). The double contact 38.50 of the two switches 24.26 is in respective engagement with the fixed contacts 42.54. The first auxiliary switch 24 indicates the change of position of the contacts of the circuit breaker block 11. The passage to the left of the lever 20 towards the open position, ensures automatic resetting of the latching 68. The second signaling switch 26 indicates the nature of the opening, reflecting the triggering of the circuit breaker block fault 11. This fault is signaled by the appearance of the indicator light 100 on the front face of the housing 19. The fault signal is canceled manually by pushing the support lever 94 clockwise, using a screwdriver resting on step 118.

En l'absence de défaut et, lors d'une ouverture manuelle du disjoncteur 10 par les manettes 16 du bloc disjoncteur 11, la rotation de la manette 20 vers la position d'ouverture entraîne le levier de commande 106 dans le sens inverse des aiguilles d'une montre de manière à interdire tout mouvement du levier support 94 par blocage de la saillie 104 (voir figure 7). La coopération de la saillie 104 avec le secteur 110 circulaire du levier de commande 106 n'entrave pas le mouvement de pivotement de la manette 20, mais maintient positivement le bras de contact 48 contre le contact fixe 52. Le deuxième interrupteur 26 reste inactif et n'indique pas de signalisation de défaut. Par contre, le premier interrupteur 24 change de position par pivotement de la platine 62 imposée par la bielle de transmission 66 accouplée à la manette 20. Le contact double 38 vient en engagement avec le contact fixe 42, et le premier interrupteur 24 auxiliaire indique le changement de position des contacts du bloc disjoncteur 11.In the absence of a fault and, when the circuit breaker 10 is opened manually by the handles 16 of the circuit breaker block 11, the rotation of the handle 20 towards the open position drives the control lever 106 in the opposite direction to the needles of a watch so as to prevent any movement of the support lever 94 by blocking the projection 104 (see FIG. 7). The cooperation of the projection 104 with the circular sector 110 of the control lever 106 does not hamper the pivoting movement of the lever 20, but positively maintains the contact arm 48 against the fixed contact 52. The second switch 26 remains inactive and does not indicate a fault signal. By cons, the first switch 24 changes position by pivoting the plate 62 imposed by the transmission rod 66 coupled to the lever 20. The double contact 38 comes into engagement with the fixed contact 42, and the first auxiliary switch 24 indicates the change of position of the contacts of the circuit breaker block 11.

SELECTEUR EN POSITION VERROUILLEESELECTOR IN LOCKED POSITION

Le bec d'accrochage 112 est verrouillée par le curseur 113 du sélecteur 114, et le levier de commande reste bloqué dans la position de la figure 2 indépendamment du mouvement de pivotement de la manette 20. La saillie 104 n'interfère plus avec le secteur 110, et le levier support 94 pivote avec la platine 62 lors d'un déclenchement automatique ou d'une ouverture manuelle par l'opérateur. L'état du deuxième interrupteur 26 est alors identique à celui du premier interrupteur 24 quel que soit le mode de fonctionnement du disjoncteur 10. Le bloc auxiliaire 14 possède alors deux interrupteurs auxiliaires 24,26 qui indiquent exclusivement l'état des contacts du bloc disjoncteur 11.The hooking spout 112 is locked by the cursor 113 of the selector 114, and the control lever remains locked in the position of FIG. 2 independently of the pivoting movement of the lever 20. The projection 104 no longer interferes with the sector 110, and the support lever 94 pivots with the plate 62 during an automatic triggering or a manual opening by the operator. The state of the second switch 26 is then identical to that of the first switch 24 regardless of the operating mode of the circuit breaker 10. The auxiliary unit 14 then has two auxiliary switches 24, 26 which exclusively indicate the state of the contacts of the circuit breaker unit 11.

La présence du ressort accumulateur 90 dans le mécanisme 22 d'actionnement du bloc auxiliaire 14 permet de transmettre vers l'extérieur un ordre de commande dérivé du mouvement de pivotement de la platine 62 (voir flèche F3, figure 3). Cet ordre de commande peut être appliqué à d'autres auxiliaires électriques grâce à un embout 126 (figure 3) se trouvant à l'opposé de la tige 80 appartenant à la deuxième liaison mécanique 86. L'embout 126 comporte un trou borgne dans lequel peut s'introduire une liaison mécanique de déclenchement appartenant à l'un des auxiliaires accolés, par exemple un déclencheur à manque de tension MN, un relais MX à bobine d'émission, ou un autre bloc auxiliaire de signalisation.The presence of the accumulator spring 90 in the mechanism 22 for actuating the auxiliary unit 14 makes it possible to transmit to the outside a control order derived from the pivoting movement of the plate 62 (see arrow F3, FIG. 3). This control order can be applied to other electrical auxiliaries by means of an end piece 126 (FIG. 3) located opposite the rod 80 belonging to the second mechanical connection 86. The end piece 126 has a blind hole in which A mechanical triggering link belonging to one of the adjoining auxiliaries can be introduced, for example an undervoltage release MN, a relay MX with transmission coil, or another auxiliary signaling block.

La figure 8 montre l'association d'un bloc disjoncteur 11 et de trois blocs auxiliaires 14a, 14b, 14c de contrôle et de signalisation pour former un disjoncteur automatique 100 modulaire. Les trois blocs auxiliaires sont identiques du type décrit en référence aux figures 2 à 5. Le bloc auxiliaire 14a reçoit en premier l'ordre de déclenchement (flèche F2) du bloc disjoncteur 11, et transmet ultérieurement par son mécanisme 22, un deuxième ordre de déclenchement (flèche F3) au bloc auxiliaire 14b intermédiaire. Ce dernier transmet finalement un troisième ordre de déclenchement (flèche F4) au dernier bloc auxiliaire 14c. Une telle association permet d'obtenir un déclenchement en cascade des blocs auxiliaires 14a, 14b, 14c à partir du bloc disjoncteur 11.FIG. 8 shows the association of a circuit breaker block 11 and three auxiliary control and signaling blocks 14a, 14b, 14c to form a modular automatic circuit breaker 100. The three auxiliary blocks are identical to the type described with reference to FIGS. 2 to 5. The auxiliary block 14a first receives the triggering order (arrow F2) from the block circuit breaker 11, and subsequently transmits by its mechanism 22, a second tripping order (arrow F3) to the auxiliary auxiliary block 14b. The latter finally transmits a third trip order (arrow F4) to the last auxiliary block 14c. Such an association makes it possible to obtain a cascade tripping of the auxiliary blocks 14a, 14b, 14c from the circuit breaker block 11.

Sur la figure 9, un bloc auxiliaire 14 est intercalé entre le bloc disjoncteur 11 et un relais équipé d'une bobine d'émission MX ou d'une bobine à manque de tension MN. L'ordre de déclenchement émis par le relais (voir flèche F5) est d'abord transmis au bloc auxiliaire 14, puis au bloc disjoncteur 11 (voir flèche F6). Une telle association permet d'obtenir un disjoncteur automatique 200 ayant un déclenchement en cascade du bloc auxiliaire 14 et du bloc disjoncteur 11 à partir du relais.In FIG. 9, an auxiliary block 14 is interposed between the circuit breaker block 11 and a relay equipped with a transmission coil MX or with an undervoltage coil MN. The tripping order sent by the relay (see arrow F5) is first transmitted to the auxiliary block 14, then to the circuit breaker block 11 (see arrow F6). Such an association makes it possible to obtain an automatic circuit breaker 200 having a trip in cascade of the auxiliary block 14 and of the circuit breaker block 11 from the relay.

Dans les disjoncteurs modulaires 100,200 des figures 8 et 9, les blocs auxiliaires 14, 14a, 14b, 14c, et le relais à MX ou MN sont obligatoirement agencés à gauche du bloc disjoncteur 11. Un bloc différentiel 150 (montré en pointillé) peut être adapté à la partie droite du bloc disjoncteur (11).In the modular circuit breakers 100,200 of FIGS. 8 and 9, the auxiliary blocks 14, 14a, 14b, 14c, and the relay at MX or MN are necessarily arranged to the left of the circuit breaker block 11. A differential block 150 (shown in dotted lines) can be suitable for the right side of the circuit breaker block (11).
