Abstract

A modular breaker is formed by associating an auxiliary, in particular differential or emission, tripping block 12 with a multipole breaker block 10. The mechanism 46 for controlling the tripping block 12 is driven by a relay 45 and is connected to the breaker block 10 by a first mechanical link 48 with tripping finger 52, and a second mechanical link 50 with rearming handle 54. In the event of discord between the handles 24, 54 when an unarmed tripping block 12 is associated with a closed breaker block 10, the tripping finger 52 of the first link 48 interacts with a pad 64 for operating the trip bar 26 in order to cause the forced tripping of the breaker block 10. The opening of the latter then allows the coupling of the handles 24, 54 in order to form the second mechanical rearming link 50 which may be one-way or two-way. <IMAGE>

Description

L'invention est relative à un disjoncteur modulaire à bloc déclencheur auxiliaire, notamment différentiel ou à émission, susceptible d'être accolé et accouplé à un bloc disjoncteur multipolaire ayant une pluralité de pôles juxtaposés, chaque pôle dudit bloc disjoncteur comportant des contacts séparables et un premier mécanisme d'actionnement desdits contacts, piloté soit manuellement par une manette de commande à deux positions stables d'ouverture et de fermeture du disjoncteur, soit automatiquement par un déclencheur principal coopérant avec une barre de déclenchement en cas de surcharge ou de court-circuit, ledit bloc déclencheur auxiliaire renfermant un relais électromagnétique associé à un deuxième mécanisme de commande comprenant une manette de réarmement du bloc déclencheur et une première liaison mécanique de déclenchement susceptible de transmettre l'ordre de déclenchement du relais à la barre de déclenchement par engagement d'un doigt du deuxième mécanisme dans un orifice ménagé dans le boîtier isolant du pôle voisin.The invention relates to a modular circuit breaker with auxiliary trip block, in particular differential or emission, capable of being coupled and coupled to a multipole circuit breaker block having a plurality of juxtaposed poles, each pole of said circuit breaker block comprising separable contacts and a first mechanism for actuating said contacts, controlled either manually by a control handle with two stable opening and closing positions of the circuit breaker, or automatically by a main trip device cooperating with a trip bar in the event of an overload or short-circuit , said auxiliary trip unit containing an electromagnetic relay associated with a second control mechanism comprising a reset lever for the trip unit and a first mechanical trip link capable of transmitting the trip order of the relay to the trip bar by engagement of a second mechanism finger in a mena opening located in the insulating housing of the neighboring pole.

Un disjoncteur différentiel connu du genre mentionné est décrit dans le brevet français 2 437 692 de la demanderesse. L'accouplement du bloc différentiel au bloc disjoncteur est effectué par l'installateur qui doit s'assurer de l'engagement correct du doigt de déclenchement du bloc déclencheur dans le premier mécanisme du pôle voisin, et de l'interconnexion des manettes autorisant le réarmement du bloc déclencheur par l'actionnement du premier mécanisme. Si ces consignes ne sont pas respectées, le bloc déclencheur différentiel est inopérant. Le risque d'un accouplement défectueux est possible en cas de discordance des manettes, notamment lorsque l'installateur tente d'accoupler un bloc déclencheur désarmé à un bloc disjoncteur armé et fermé.A known differential circuit breaker of the kind mentioned is described in French patent 2,437,692 of the applicant. The differential block is coupled to the circuit breaker block by the installer, who must ensure that the release finger of the release block is correctly engaged in the first mechanism of the neighboring pole, and that the handles allow the resetting to be reset. of the trigger block by actuation of the first mechanism. If these instructions are not followed, the differential trip unit is inoperative. The risk of a faulty coupling is possible in the event of a mismatch between the levers, especially when the installer attempts to couple a disarmed trip unit to an armed and closed circuit breaker unit.

L'objet de l'invention consiste à réaliser un accouplement parfait du bloc disjoncteur et du bloc déclencheur auxiliaire d'un disjoncteur modulaire, indépendamment de l'état armé ou déclenché des blocs.The object of the invention is to achieve perfect coupling of the circuit breaker block and the auxiliary trip block of a modular circuit breaker, regardless of the armed or tripped state of the blocks.

Le disjoncteur selon l'invention est caractérisé en ce que un moyen de contrôle est agencé pour transformer le mouvement de rapprochement des deux blocs en un mouvement d'ajustement automatique des manettes de commande et de réarmement des premier et deuxième mécanismes, de manière à éviter toute discordance entre lesdites manettes, notamment lors de l'association d'un bloc déclencheur désarmé à un bloc disjoncteur fermé.The circuit breaker according to the invention is characterized in that a control means is arranged to transform the movement of bringing the two blocks closer into a movement of automatic adjustment of the control levers and of resetting of the first and second mechanisms, so as to avoid any discrepancy between said levers, in particular when a disarmed trip unit is associated with a closed circuit breaker unit.

Selon un premier mode de réalisation, le doigt de déclenchement de la première liaison mécanique est susceptible de coopérer avec une rampe d'actionnement de la barre de déclenchement pour provoquer le déclenchement forcé du bloc disjoncteur, le mouvement de rapprochement des blocs étant transformé en un mouvement de pivotement de la barre de déclenchement vers la position déclenchée.According to a first embodiment, the trigger finger of the first mechanical connection is capable of cooperating with an actuating ramp of the trigger bar to cause the forced tripping of the circuit breaker block, the movement of approaching the blocks being transformed into a pivoting movement of the trigger bar towards the triggered position.

Le déclenchement forcé du bloc disjoncteur par l'action du doigt sur la rampe intervient avant l'accouplement des manettes des premier et deuxième mécanismes grâce à un jeu prédéterminé qui subsiste entre lesdites manettes lorsque le doigt vient en contact avec la rampe.The forced tripping of the circuit breaker block by the action of the finger on the ramp occurs before the handles of the first and second mechanisms are coupled thanks to a predetermined clearance which remains between said handles when the finger comes into contact with the ramp.

Le deuxième mécanisme est équipé d'une deuxième liaison mécanique de réarmement du bloc déclencheur comportant un ergot de transmission susceptible d'entraîner la manette de réarmement vers la position armée lors de l'actionnement manuel de la manette du premier mécanisme vers la position de fermeture du bloc disjoncteur. Cette deuxième liaison mécanique peut être unidirectionnelle ou bidirectionnelle.The second mechanism is equipped with a second mechanical link for resetting the trip unit comprising a transmission lug capable of driving the reset handle to the armed position during manual actuation of the handle of the first mechanism to the closed position. of the circuit breaker block. This second mechanical link can be unidirectional or bidirectional.

Le centrage des deux blocs est assuré par des pions de positionnement du bloc déclencheur pouvant s'engager dans des trous de guidage du pôle adjacent. La longueur du doigt de la première liaison mécanique de déclenchement est inférieure à celle des pions de positionnement.The centering of the two blocks is ensured by positioning pins of the trigger block which can engage in guide holes of the adjacent pole. The finger length of the first mechanical trigger link is lower than that of the positioning pins.

Selon un deuxième mode de réalisation, ledit moyen de contrôle comporte un cliquet intégré dans la manette de réarmement du bloc déclencheur de manière à provoquer un mouvement de basculement de la manette vers la position armée du deuxième mécanisme.According to a second embodiment, said control means comprises a pawl integrated in the reset lever of the trip unit so as to cause a rocking movement of the handle towards the armed position of the second mechanism.

Sur les figures, un bloc déclencheur 12 auxiliaire du type différentiel ou à émission est accolé et accouplé à un bloc disjoncteur 10 bipolaire pour constituer un disjoncteur differentiel ou un disjoncteur télécommandé.In the figures, an auxiliary trip unit 12 of the differential or emission type is attached and coupled to a two-pole circuit breaker unit 10 to constitute a differential circuit breaker or a remote-controlled circuit breaker.

Le bloc disjoncteur 10 est formé par la juxtaposition de deux pôles 14,16 standards comportant chacun une paire de bornes de raccordement, une paire de contacts 18,20 séparables (figure 5 et 6) et un premier mécanisme 22 d'actionnement piloté soit manuellement par une manette 24 de commande à deux positions stables d'ouverture et de fermeture du disjoncteur, soit automatiquement par un déclencheur principal magnétothermique (non représenté) actionnant une barre de déclenchement 26 commune en cas de surcharge ou de court-circuit. Les manettes 24 des deux pôles 14,16 sont reliées mécaniquement entre elles par une barrette 28 commune. Le mécanisme 22 (figures 5 et 6) de chaque pôle 14,16 est du type décrit dans la demande de brevet européen n° 86 402 267, et comprend un levier de déclenchement 30 monté à pivotement sur un axe 32 porté par une platine 34 susceptible de tourner autour d'un pivot 36 lors de l'ouverture et de la fermeture du disjoncteur. Une biellette 38 de transmission est intercalée entre la manette 24 et un accrochage (non représenté) de la platine 34, ledit accrochage étant déverrouillé par le levier de déclenchement 30 lors d'un défaut détecté par le déclencheur magnétothermique. Cet ordre de déclenchement peut être transmis au pôle voisin du bloc disjoncteur 10 par un doigt 44 (figures 5 et 9), formé par une aiguille auxiliaire reliant les extensions des leviers de déclenchement 30 des deux pôles. Les faces opposées du boîtier 40 isolant de chaque pôle comportent une paire d'orifices 42 alignés, destinés à assurer l'émission et la réception des ordres de déclenchement entre les pôles du bloc disjoncteur 10 et le bloc déclencheur 12. L'émission au niveau d'un pôle s'exerce toujours vers la gauche, tandis que la réception provient de la droite (figure 9).The circuit breaker block 10 is formed by the juxtaposition of two standard 14.16 poles each comprising a pair of connection terminals, a pair of separable 18.20 contacts (FIGS. 5 and 6) and a first actuation mechanism 22 controlled either manually by a control lever 24 with two stable positions for opening and closing the circuit breaker, or automatically by a main thermomagnetic trip device (not shown) actuating a common trip bar 26 in the event of an overload or short-circuit. The levers 24 of the two poles 14, 16 are mechanically linked together by a common bar 28. The mechanism 22 (Figures 5 and 6) of each pole 14,16 is of the type described in European patent application No. 86 402 267, and comprises a trigger lever 30 pivotally mounted on an axis 32 carried by a plate 34 capable of rotating around a pivot 36 when the circuit breaker opens and closes. A transmission link 38 is interposed between the lever 24 and an attachment (not shown) of the plate 34, said attachment being unlocked by the trigger lever 30 during a fault detected by the magnetothermal trigger. This tripping order can be transmitted to the pole next to the block circuit breaker 10 by a finger 44 (Figures 5 and 9), formed by an auxiliary needle connecting the extensions of the trigger levers 30 of the two poles. The opposite faces of the insulating housing 40 of each pole include a pair of aligned holes 42, intended to ensure the transmission and reception of trip orders between the poles of the circuit breaker block 10 and the trip block 12. The emission at the level a pole is always exerted towards the left, while the reception comes from the right (figure 9).

Le bloc disjoncteur 10 pourrait bien entendu comporter une juxtaposition de trois pôles protégés, ou d'un pôle de phase avec un pôle de neutre.The circuit breaker block 10 could of course include a juxtaposition of three protected poles, or of a phase pole with a neutral pole.

Le bloc déclencheur 12 auxiliaire renferme un relais électromagnétique 45 associé à un deuxième mécanisme de commande 46 (voir figures 1 à 4). Le relais 45 est alimenté par un transformateur différentiel ou par une commande à distance, de manière à émettre un ordre de déclenchement au bloc disjoncteur 10 voisin. Le mécanisme 46 du bloc déclencheur 12 est relié au bloc disjoncteur 10 par une première liaison mécanique 48 de déclenchement, montrée en détail à la partie supérieure des figures 1 à 4 et par une deuxième liaison mécanique 50 (voir partie inférieure) de réarmement du relais 45 du bloc déclencheur 12.The auxiliary trip unit 12 contains an electromagnetic relay 45 associated with a second control mechanism 46 (see FIGS. 1 to 4). Relay 45 is supplied by a differential transformer or by a remote control, so as to issue a trip order to the neighboring circuit breaker block 10. The mechanism 46 of the trip unit 12 is connected to the circuit breaker unit 10 by a first mechanical trip link 48, shown in detail in the upper part of FIGS. 1 to 4 and by a second mechanical link 50 (see lower part) for resetting the relay 45 of the trip unit 12.

La première liaison mécanique 48 transmet l'ordre de déclenchement du relais 45 à la barre de déclenchement 26 par engagement d'un doigt 52 du mécanisme 46 dans l'orifice 42 situé dans la face de droite du pôle 16. La deuxième liaison mécanique 50 du mécanisme 46 comporte une manette 54 de réarmement équipée d'un ergot 56 d'entraînement coopérant avec la manette 24 de commande du pôle 16. L'entraînement de la manette 54 de réarmement du bloc déclencheur 12 par la manette 24 du bloc disjoncteur 10 est unidirectionnel dans le sens de la fermeture du mécanisme 22 d'actionnement. Il n' y a aucune liaison positive entre les manettes 54,24 dans le sens opposé d'ouverture du disjoncteur.The first mechanical link 48 transmits the triggering order of the relay 45 to the trigger bar 26 by engagement of a finger 52 of the mechanism 46 in the orifice 42 located in the right face of the pole 16. The second mechanical link 50 of the mechanism 46 comprises a reset handle 54 fitted with a drive lug 56 cooperating with the handle 24 for controlling the pole 16. The drive of the handle 54 for resetting the trip unit 12 by the handle 24 of the circuit breaker unit 10 is unidirectional in the direction of closing the actuating mechanism 22. There is no positive connection between the levers 54,24 in the opposite direction of opening of the circuit breaker.

Le mouvement de réarmement du mécanisme 46 après déclenchement par le bloc déclencheur 12 auxiliaire s'opère en deux phases distinctes:
- durant la première phase de transmission de l'ordre de déclenchement du relais 45 par le doigt 52 à la barre 26, le disjoncteur s'ouvre et un levier d'armement (non représenté) du mécanisme 46 repousse automatiquement le relais 45 vers la position réarmée. La manette 54 se trouve par contre en position déclenchée, la deuxième liaison mécanique 50 étant inactive.
- durant la deuxième phase, la fermeture manuelle de la manette 24 du bloc disjoncteur 10 fait intervenir la deuxième liaison 50 qui entraîne positivement la manette 54 vers la position réarmée, et libère le relais 45 de la force de rappel du levier d'armement du mécanisme 46. Le bloc déclencheur 12 auxiliaire est alors prêt à envoyer un nouveau ordre de déclenchement au bloc disjoncteur 10.The reset movement of the mechanism 46 after triggering by the auxiliary trigger block 12 takes place in two distinct phases:
- during the first phase of transmitting the triggering order of relay 45 by finger 52 to the bar 26, the circuit breaker opens and an arming lever (not shown) of the mechanism 46 automatically pushes the relay 45 towards the reset position. The lever 54 is on the other hand in the triggered position, the second mechanical connection 50 being inactive.
- during the second phase, the manual closing of the handle 24 of the circuit breaker block 10 involves the second link 50 which positively drives the handle 54 to the reset position, and releases the relay 45 from the restoring force of the arming lever of the mechanism 46. The auxiliary trip unit 12 is then ready to send a new trip order to the circuit breaker unit 10.

L'accouplement latéral des deux liaisons mécaniques 48,50 du bloc déclencheur 12 auxiliaire sur le bloc disjoncteur 10 doit s'effectuer sans erreur. Le boîtier 59 du bloc déclencheur 12 comprend à cet effet des pions 60 de positionnement susceptibles de s'engager dans des trous 61 de guidage ménagés dans le boîtier 40 du pôle 16 (figure 7). les pions 60 et le doigt 52 de déclenchement du bloc déclencheur 12 font saillie de la face latérale interne du boîtier 59 en s'étendant parallèlement l'un à l'autre, le doigt 52 ayant une longueur inférieure à celle des pions 60. Lors de l'accolement des deux blocs 10,12, le doigt 52 de la première liaison mécanique 48 traverse l'orifice 42 de droite du pôle 16, et coopère soit avec un épaulement 62, soit avec une rampe 64 du levier de déclenchement 30 selon l'état armé ou déclenché des mécanismes 22,46 de commande des blocs 10,12. L'épaulement 62 s'étend parallèlement au doigt 52 de déclenchement et est situé entre la rampe 64 et un logement 66 borgne du levier 30.The lateral coupling of the two mechanical connections 48.50 of the auxiliary trip unit 12 on the circuit breaker unit 10 must be carried out without error. The housing 59 of the trip unit 12 for this purpose comprises positioning pins 60 capable of engaging in guide holes 61 formed in the housing 40 of the pole 16 (Figure 7). the pins 60 and the trigger finger 52 of the trigger block 12 protrude from the internal lateral face of the housing 59 extending parallel to each other, the finger 52 having a length less than that of the pins 60. During of the joining of the two blocks 10,12, the finger 52 of the first mechanical connection 48 crosses the orifice 42 on the right of the pole 16, and cooperates either with a shoulder 62, or with a ramp 64 of the trigger lever 30 according to the armed or triggered state of the mechanisms 22,46 for controlling the blocks 10,12. The shoulder 62 extends parallel to the trigger finger 52 and is located between the ramp 64 and a housing 66 blind lever 30.

Différents cas de montage peuvent se présenter lors de l'association des blocs 10,12 par le client :
- lorsque le bloc disjoncteur 10 est ouvert (manette 24 sur 0 aux figures 1 et 2), le levier de déclenchement 30 de chaque pôle 14,16 se trouve en position relevée (figure 6) correspondant à la position déclenchée de la barre de déclenchement 26. La pénétration du doigt 52 de déclenchement dans le pôle 16, et l'accouplement des manettes 54,24 par l'ergot 56 de la deuxième liaison mécanique 50 s'effectuent sans problèmes, indépendamment de la position déclenchée (0 sur figure 1) ou armée (I sur figure 2) de la manette 54 du bloc déclencheur 12 auxiliaire.
- lorsque le bloc disjoncteur 10 est fermé (manette 24 sur I aux figures 3 et 4), le levier de déclenchement 30 de chaque pôle 14,16 est en position abaissée (figure 5) correspondant à la position armée de la barre de déclenchement 26. Si la manette 54 du bloc déclencheur 12 se trouve elle-même en position armée (I sur figure 3), l'accolement des blocs 10,12 est rendu possible grâce à la pénétration du doigt 52 de déclenchement, et de l'accouplement des manettes 54,24. On remarque que la barrette 28 commune des manettes 24 du bloc disjoncteur 10 est placé en dessous de la manette 56 du bloc déclencheur 12 auxiliaire. Cette disposition est indispensable pour constituer la deuxième liaison mécanique 50 de réarmement. Si la manette 54 est positionnée dans la position déclenchée (0 sur figure 4), les manettes 54,24 se trouvent initialement en discordance. Le doigt 52 de déclenchement du bloc déclencheur 12 vient buter contre la rampe 64 (figures 7 et 8), et fait pivoter le levier 30 et la barre de déclenchement 26 vers la position déclenchée entraînant l'ouverture du bloc disjoncteur 10. Ce mouvement pivotant de déclenchement forcé résulte de la transformation du mouvement d'accolement par l'action du doigt 52 sur la rampe 64. Le déclenchement forcé intervient avant l'accouplement des manettes 24,54 grâce à un jeu J (figure 7) prédéterminé qui subsiste entre ces dernières lorsque le bout du doigt 52 vient en contact avec la rampe 64. Après déclenchement forcé, on se retrouve dans le cas du montage de la figure 1, et l'association des blocs 10,12 est possible. La manette 24 du bloc disjoncteur 10 est placée en dessous de la manette 54 du bloc déclencheur 12 pour établir la deuxième liaison mécanique 50. la fermeture des contacts du bloc disjoncteur 10 par déplacement manuel de la manette 24 vers la position I (figure 5) entraîne alors la manette 54 vers la position armée du bloc déclencheur 12 auxiliaire.Different mounting cases can arise during the association of blocks 10,12 by the customer:
- when the circuit breaker block 10 is open (lever 24 on 0 in Figures 1 and 2), the trigger lever 30 of each pole 14,16 is in the raised position (Figure 6) corresponding to the triggered position of the trigger bar 26. The penetration of the trigger finger 52 into the pole 16, and the coupling of the levers 54, 24 by the lug 56 of the second mechanical connection 50 takes place without problems, independently of the triggered position (0 in FIG. 1 ) or armed (I in FIG. 2) of the lever 54 of the auxiliary trip unit 12.
- when the circuit breaker block 10 is closed (handle 24 on I in FIGS. 3 and 4), the trigger lever 30 of each pole 14,16 is in the lowered position (FIG. 5) corresponding to the armed position of the trigger bar 26 If the lever 54 of the trigger block 12 is itself in the armed position (I in FIG. 3), the joining of the blocks 10, 12 is made possible by the penetration of the trigger finger 52, and of the coupling joysticks 54.24. It will be noted that the common bar 28 of the levers 24 of the circuit breaker block 10 is placed below the lever 56 of the auxiliary trip unit 12. This provision is essential to constitute the second mechanical connection 50 for rearming. If the handle 54 is positioned in the triggered position (0 in FIG. 4), the handles 54, 24 are initially in discrepancy. The trigger 52 trigger finger 12 abuts against the ramp 64 (Figures 7 and 8), and rotates the lever 30 and the trigger bar 26 to the tripped position causing the opening of the circuit breaker block 10. This pivoting movement of forced triggering results from the transformation of the joining movement by the action of finger 52 on the ramp 64. The forced triggering occurs before the coupling of the levers 24.54 thanks to a predetermined clearance J (FIG. 7) which remains between them when the tip of the finger 52 comes into contact with the ramp 64. After forced release, we find ourselves again in the case of the assembly of FIG. 1, and the association of blocks 10,12 is possible. The handle 24 of the circuit breaker unit 10 is placed below the handle 54 of the trip unit 12 to establish the second mechanical connection 50. the closure of the contacts of the circuit breaker unit 10 by manual movement of the handle 24 towards position I (FIG. 5) then drives the handle 54 to the armed position of the auxiliary trigger unit 12.

La deuxième liaison mécanique 50 pourrait bien entendu être bidirectionnelle par réunion permanente au moyen de l'ergot 56 des deux manettes 24,54 de commande des blocs 10,12 accolés. Le mécanisme 46 du bloc déclencheur 12 serait modifié, tel que le mouvement de réarmement du relais 45 serait dérivé du mouvement d'ouverture du disjoncteur.The second mechanical connection 50 could of course be bidirectional by permanent assembly by means of the lug 56 of the two levers 24,54 for controlling the adjoining blocks 10,12. The mechanism 46 of the trip unit 12 would be modified, such that the reset movement of the relay 45 would be derived from the opening movement of the circuit breaker.

La deuxième liaison 50 pourrait d'autre part être totalement supprimée, et le réarmement séparé du bloc déclencheur 12 auxiliaire serait dans ce cas opéré manuellement par actionnement de la manette 54 avant la fermeture du bloc disjoncteur 10.The second link 50 could also be completely eliminated, and the separate resetting of the auxiliary trip unit 12 would in this case be done manually by actuation of the lever 54 before the circuit breaker unit 10 closes.

Dans ces deux variantes, le déclenchement forcé du bloc disjoncteur 10 par action du doigt 52 sur la rampe 64 subsiste dans le cas d'une association par le client d'un bloc déclencheur 12 désarmé à un bloc disjoncteur 10 armé.In these two variants, the forced tripping of the circuit breaker block 10 by action of the finger 52 on the ramp 64 remains in the case of the client's association of a disarmed trip block 12 with an armed circuit breaker block 10.

La figure 9 montre schématiquement la transmission du mouvement de déclenchement entre le bloc déclencheur 12 et les pôles 14,16 du bloc disjoncteur 10. La barre de déclenchement 26 est modulaire et est constituée par l'emboîtement transversal des doigts 52,44 avec les leviers de déclenchements 30 des pôles 16,14. La barre 26 de déclenchement du disjoncteur sert au déclenchement multipolaire, c'est à dire entre les deux pôles 12,14, et au déclenchement par le bloc auxiliaire 12. Le fractionnement de la barre 26 permet d'obtenir des mouvements différents dans les deux blocs 10,12. Dans le cas de la liaison multipolaire, le doigt 44 de liaison entre les leviers 30 des deux pôles 14,l6 pénètre complètement dans le logement 66 borgne ménagé dans le levier de déclenchement 30 du pôle 14, et y reste prisonnier. L'autre extrémité du doigt 44 est fixée dans un trou du levier 30 appartenant au pôle 16. Cette liaison bidirectionnelle autorise la transmission du mouvement de déclenchement dans les deux sens, c'est à dire du pôle 14 vers le pôle 16, et vice-versa. Au niveau de l'accouplement avec le bloc de déclenchement auxiliaire 12, la liaison est unidirectionnelle, car le doigt 52 de déclenchement du mécanisme 46 ne pénètre pas dans le logement 66 du levier 30 appartenant au pôle 16, mais coopère avec l'épaulement 62 dans un seul sens de rotation de la barre 26. La transmission du mouvement de déclenchement s'effectue uniquement vers la gauche, c'est à dire du bloc déclencheur 12 vers le pôle 16, mais pas dans le sens inverse. Le déclenchement du bloc disjoncteur 10 à la suite d'une surcharge ou d'un court-circuit ne provoquera pas le déclenchement du bloc auxiliaire 12.FIG. 9 diagrammatically shows the transmission of the tripping movement between the tripping block 12 and the poles 14, 16 of the circuit breaker block 10. The tripping bar 26 is modular and is constituted by the transverse interlocking of the fingers 52, 44 with the levers tripping 30 of the poles 16,14. The circuit breaker trip bar 26 is used for multipole trip, that is to say between the two poles 12,14, and when triggered by the auxiliary block 12. The splitting of the bar 26 makes it possible to obtain different movements in the two blocks 10,12. In the case of the multipole connection, the connecting finger 44 between the levers 30 of the two poles 14, 16 penetrates completely into the blind housing 66 formed in the trigger lever 30 of the pole 14, and remains trapped there. The other end of the finger 44 is fixed in a hole in the lever 30 belonging to the pole 16. This bidirectional connection allows the transmission of the tripping movement in both directions, that is to say from the pole 14 towards the pole 16, and vice -versed. At the coupling with the auxiliary trigger block 12, the connection is unidirectional, because the trigger finger 52 of the mechanism 46 does not enter the housing 66 of the lever 30 belonging to the pole 16, but cooperates with the shoulder 62 in a single direction of rotation of the bar 26. The transmission of the triggering movement takes place only to the left, that is to say from the trigger block 12 to the pole 16, but not in the opposite direction. The tripping of the circuit breaker block 10 following an overload or a short circuit will not cause the tripping of the auxiliary block 12.

L'emboîtement du doigt de déclenchement 52, du bloc auxiliaire 12 dans le pôle 16 voisin s'effectue directement sans aucune pièce intermédiaire de liaison, étant donné que le doigt 52 fait partie de la première liaison mécanique 48 intégrée dans le mécanisme 46.The engagement of the trigger finger 52, of the auxiliary block 12 in the neighboring pole 16 takes place directly without any intermediate connecting part, since the finger 52 is part of the first mechanical connection 48 integrated in the mechanism 46.

La variante de la figure 10 ne prévoit pas de déclenchement forcé en cas de discordance des manettes 24,54, mais un rappel automatique de la manette 54 du bloc déclencheur 12 au moyen d'un cliquet 70. Ce dernier est intégré avantageusement dans l'ergot 56 de la manette 54. Lorsque le bloc disjoncteur 10 est fermé, et que le bloc déclencheur 12 se trouve en position désarmée, l'accolement des deux blocs 10,12 provoque sous l'action du cliquet 70 un mouvement de basculement de la manette 54 vers la position armée, c'est à dire en regard avec la manette 24.The variant of FIG. 10 does not provide for forced triggering in the event of discordance of the levers 24.54, but an automatic return of the lever 54 of the trigger block 12 by means of a ratchet 70. The latter is advantageously integrated in the lug 56 of the handle 54. When the circuit breaker block 10 is closed, and the trip block 12 is in the disarmed position, the joining of the two blocks 10,12 causes under the action of the pawl 70 a tilting movement of the lever 54 towards the armed position, that is to say facing lever 24.
