The invention relates to a low voltage electric circuit breaker comprising:
  • a plurality of juxtaposed poles,
  • a molded case in which said poles are housed, said case having a base, a two-part cover, and compartments formed in the cover,
  • for each pole at least one fixed contact and one movable contact, and a section of bar carrying the movable contact,

Un disjoncteur connu du genre mentionné, est personnalisé lors de son installation en lui adjoignant des blocs auxiliaires adaptés à l'application ou à l'installation électrique correspondante. Ces blocs auxiliaires sont par exemple, des contacts de signalisation de la position ouvert ou fermée des contacts, ou de signalisation d'un déclenchement sur défaut, ou de toute autre commande, ou signalisation. Ces blocs auxiliaires coopèrent électriquement et ou mécaniquement avec des éléments du disjoncteur, et ils sont logés dans des compartiments accessibles après enlèvement d'une plaque de protection ou d'un couvercle. Les compartiments sont avantageusement isolés électriquement des autres parties du disjoncteur pour permettre la mise en place ou l'enlèvement des blocs auxiliaires, l'appareil étant sous tension. Chaque bloc auxiliaire est adapté à sa fonction, et sa structure et son encombrement varient selon le type de fonction assurée. A leur tour, les compartiments sont adaptés au type de blocs auxiliaires correspondants, et ils peuvent même comporter des détrompeurs évitant la mise en place d'un bloc auxiliaire inadapté.A known circuit breaker of the kind mentioned, is personalized during its installation by adding auxiliary blocks adapted to the application or the corresponding electrical installation. These auxiliary blocks are, for example, contacts for signaling the open or closed position of the contacts, or for signaling a trip on fault, or any other command, or signaling. These auxiliary blocks cooperate electrically and or mechanically with elements of the circuit breaker, and they are housed in accessible compartments after removal of a protective plate or a cover. The compartments are advantageously electrically isolated from the other parts of the circuit breaker to allow the insertion or removal of the auxiliary blocks, the device being energized. Each auxiliary unit is adapted to its function, and its structure and size vary depending on the type of function provided. In turn, the compartments are adapted to the type of corresponding auxiliary blocks, and they may even include keying pins avoiding the installation of an unsuitable auxiliary block.

La personnalisation du disjoncteur par le distributeur ou par l'installateur présente l'avantage d'une réduction des stocks, mais cette réduction est limitée par le fait qu'à chaque disjoncteur, il est possible d'adjoindre quatre ou cinq types différents de blocs auxiliaires. L'installateur ou le distributeur doit donc disposer de ces quatre ou cinq types de blocs auxiliaires, et il est fréquent que ce lot de blocs auxiliaires est livré avec le disjoncteur, les blocs inutilisés étant simplement jetés.The customization of the circuit breaker by the distributor or by the installer has the advantage of a reduction in stocks, but this reduction is limited by the fact that at each circuit breaker, it is possible to add four or five different types of blocks auxiliaries. The installer or distributor must therefore have these four or five types of auxiliary blocks, and it is frequent that this batch of auxiliary blocks is delivered with the circuit breaker, the unused blocks being simply discarded.

La présente invention a pour but de perfectionner ces disjoncteurs et de réduire le nombre de types de blocs auxiliaires.The object of the present invention is to improve these circuit breakers and to reduce the number of types of auxiliary blocks.

Le disjoncteur selon l'invention est caractérisé en ce que lesdits compartiments possèdent des formes identiques, et lesdits blocs auxiliaires sont des éléments identiques,

  • que chaque compartiment comporte un organe de commande du bloc auxiliaire associé, au moins un organe de commande d'un compartiment ayant une liaison électrique ou mécanique avec les éléments du disjoncteur, qui est différente de celle de l'organe de commande d'un autre compartiment, de sorte que ces compartiments sont affectés à des fonctions différentes,
  • et que chaque compartiment est personnalisé à une fonction donnée, laquelle est exercée par un bloc auxiliaire logé dans le compartiment.
The circuit breaker according to the invention is characterized in that said compartments have identical shapes, and said auxiliary blocks are identical elements,
  • that each compartment comprises a control member of the associated auxiliary unit, at least one control member of a compartment having an electrical or mechanical connection with the elements of the circuit breaker, which is different from that of the control member of another compartment, so these compartments are assigned to different functions,
  • and that each compartment is personalized to a given function, which is exercised by an auxiliary block housed in the compartment.

Les blocs auxiliaires sont standard et à partir d'un stock unique, l'installateur pourra personnaliser le disjoncteur et répondre aux différents besoins. Le bloc auxiliaire standard comporte au moins un contact auxiliaire actionné par un poussoir, qui coopère après mise en place dans le compartiment correspondant, avec l'organe de commande de ce compartiment. Les organes de commande des différents compartiments sont bien entendu disposés aux mêmes emplacements et effectuent la même course d'actionnement, la différence consistant dans la liaison électrique ou mécanique avec les éléments du disjoncteur.The auxiliary blocks are standard and from a single stock, the installer will be able to customize the circuit breaker and meet different needs. The standard auxiliary unit comprises at least one auxiliary contact actuated by a pusher, which cooperates after installation in the corresponding compartment, with the control member of this compartment. The control members of the different compartments are of course arranged in the same locations and perform the same actuation stroke, the difference consisting in the electrical or mechanical connection with the elements of the circuit breaker.

L'invention est avantageusement applicable à un disjoncteur du genre décrit dans le document FR-A-2.682.531 (publié le 16.4.93) de la demanderesse, dans lequel disjoncteur chaque pôle comporte une boîte en matière plastique moulée, dans laquelle est logé un tronçon de barreau portant un pont de contact mobile. Les différents pôles du disjoncteur sont juxtaposés dans un boîtier dont le couvercle comporte les compartiments de logements des blocs auxiliaires. L'un de ces compartiments, en l'occurrence de signalisation de la position des contacts du disjoncteur, comporte un organe de commande mécaniquement relié au barreau qui porte le pont de contact mobile, de façon à représenter la position des contacts et à actionner en conséquence le contact auxiliaire du bloc logé dans ce compartiment. La liaison mécanique entre le barreau porte contact et l'organe de commande de signalisation de la position des contacts, est de préférence constituée d'un coulisseau, intercalé entre deux boîtes polaires, lequel coulisseau transmet par translation les déplacements du barreau auxdits organes de commande du compartiment.
Un autre compartiment est affecté à la signalisation d'un déclenchement et ce compartiment comporte à cet effet un organe de commande qui coopère avec le crochet d'armement et de désarmement du mécanisme. Le bloc auxiliaire standard, logé dans ce compartiment, traduira ainsi la position du crochet du mécanisme et signalera un déclenchement. Le disjoncteur peut également comporter un compartiment de signalisation de déclenchement sur défaut électrique, lequel compartiment est alors disposé en regard d'un logement d'un relais de commande agissant sur la barre de déclenchement du disjoncteur. L'organe de commande de ce compartiment est alors relié à ce relais de commande pour signaler une commande de déclenchement sur défaut électrique.The invention is advantageously applicable to a circuit breaker of the type described in document FR-A-2,682,531 (published on 16.4.93) of the applicant, in which circuit breaker each pole comprises a molded plastic box, in which is housed a section of bar carrying a movable contact bridge. The different poles of the circuit breaker are juxtaposed in a box, the cover of which includes the compartments for housing the auxiliary blocks. One of these compartments, in this case signaling the position of the contacts of the circuit breaker, comprises a control member mechanically connected to the bar which carries the movable contact bridge, so as to represent the position of the contacts and to actuate in Consequently, the auxiliary contact of the block housed in this compartment. The mechanical connection between the contact carrier bar and the control member for signaling the position of the contacts, preferably consists of a slide, interposed between two pole boxes, which slide transmits by displacement the movements of the bar to said control members compartment.
Another compartment is assigned to the signaling of a trip and this compartment comprises for this purpose a control member which cooperates with the arming and disarming hook of the mechanism. The standard auxiliary unit, housed in this compartment, will thus translate the position of the mechanism hook and signal a trip. The circuit breaker can also include a tripping signaling compartment on electrical fault, which compartment is then placed opposite a housing of a control relay acting on the tripping bar of the circuit breaker. The control member of this compartment is then connected to this control relay to signal a trip command on an electrical fault.

La personnalisation du disjoncteur est particulièrement simple, puisque le distributeur ou l'installateur introduit simplement dans le compartiment affecté à la fonction désirée, un bloc auxiliaire standard. La fonction assurée par le compartiment peut être repérée par tout moyen approprié, par exemple, par une inscription. Les blocs auxiliaires inutilisés peuvent bien entendu servir pour d'autres disjoncteurs, et on évite ainsi tout gaspillage ou stock inutile.Customizing the circuit breaker is particularly simple, since the distributor or installer simply introduces a standard auxiliary block into the compartment assigned to the desired function. The function performed by the compartment can be identified by any appropriate means, for example, by registration. Unused auxiliary blocks can of course be used for other circuit breakers, thus avoiding unnecessary waste or stock.

Les compartiments sont de préférence disposés de part et d'autre du mécanisme de commande et après mise en place des blocs auxiliaires, ils sont obturés par une deuxième partie du couvercle, qui peut être une plaque formant la face avant du disjoncteur. Les blocs auxiliaires sont de préférence fixés dans le compartiment par un simple encliquetage, qui permet un démontage et un remplacement du bloc auxiliaire à la demande.The compartments are preferably arranged on either side of the control mechanism and after the auxiliary blocks have been installed, they are closed by a second part of the cover, which can be a plate forming the front face of the circuit breaker. The auxiliary blocks are preferably fixed in the compartment by a simple snap, which allows disassembly and replacement of the auxiliary block on request.

L'invention est décrite dans la suite comme étant appliquée à un disjoncteur du genre décrit dans la demande de brevet précitée, mais il est clair qu'elle est applicable à tout autre type de disjoncteurs à boîtier moulé.The invention is described below as being applied to a circuit breaker of the type described in the aforementioned patent application, but it is clear that it is applicable to any other type of molded case circuit breaker.

Sur les figures, un boîtier moulé 10 d'un disjoncteur tripolaire constitué d'une base 11 et d'un couvercle 12, contient trois boîtes 13 unipolaires disposées côte à côte. Chaque boîte 13 contient deux contacts fixes 14,15 qui coopèrent avec un pont de contact rotatif 16. Les contacts fixes 14,15 sont chacun reliés à une plage de raccordement 17,18 et à chaque paire de contacts 14,16; 15,16 est associée une chambre de coupure 19. Le pont de contact 16 est monté flottant dans un tronçon de barreau 20 qui lui communique les mouvements d'ouverture et de fermeture des contacts 14,15,16. Les tronçons de barreau 20 des trois boîtes 13 sont solidarisés par des barres 21 accouplées à un mécanisme de commande, désigné par le repère général 22. Le mécanisme 22 est disposé au dessus du pôle central du disjoncteur et il est solidarisé à la boîte 13 de ce pôle central par deux flasques latéraux espacés 23,24 qui encadrent le mécanisme 22. Sur les flasques 23,24 est articulée une poignée de commande 25 qui fait saillie du couvercle 12. Sur les flasques 23,24 est également articulée par un axe 26, une manivelle 27 traversée par les barres 21 pour commander la rotation des tronçons de barreau 20. Une genouillère 28 relie la manivelle 27 à un crochet 29, lui même articulé par un axe 30, sur les flasques 23,24. L'extrémité 31 du crochet 29, opposée à l'axe 30 porte une surface de verrouillage 32 susceptible de coopérer avec un verrou 33. L'axe 34 de la genouillère 28 est relié par un ressort 35 à la poignée 25. Dans la position fermée du disjoncteur, représentée aux figures 5 et 7, le ressort 35 sollicite la genouillère 28 en position d'extension, tendant à faire tourner les tronçons de barreau 20, dans le sens inverse des aiguilles d'une montre, pour maintenir les contacts 14,15,16, en position fermée. Un pivotement vers la droite sur les figures 5 et 7 de la poignée 25 déplace la ligne d'action du ressort 35 en provoquant la brisure de la genouillère 28 et la rotation des tronçons de barreau 20 dans le sens des aiguilles d'une montre, pour ouvrir les contacts 14,15,16. L'actionnement du verrou 33 provoque également l'ouverture du disjoncteur, par libération du crochet 29, qui pivote dans le sens inverse des aiguilles d'une montre vers la position désarmée, représentée sur la figure 8, entraînant la manivelle 27 et les tronçons de barreau 20 vers la position d'ouverture des contacts 14,15,16. Le réarmement du mécanisme 22 résulte du déplacement de la poignée 25 vers la position d'ouverture et il suffit ensuite de pivoter la poignée en direction inverse pour fermer le disjoncteur. Le verrou 33 est commandé par un bloc déclencheur 36 associé ou incorporé au boîtier moulé 10. Un tel disjoncteur est décrit dans le document FR-A-2.687.249 (publié le 13.8.93) de la demanderesse, et le lecteur se référera avantageusement à cette demande pour de plus amples détails sur le fonctionnement et la structure de ce disjoncteur.In the figures, a molded case 10 of a three-pole circuit breaker consisting of a base 11 and a cover 12, contains three single-pole boxes 13 arranged side by side. Each box 13 contains two fixed contacts 14,15 which cooperate with a rotary contact bridge 16. The fixed contacts 14,15 are each connected to a connection pad 17,18 and to each pair of contacts 14,16; 15,16 is associated with a switching chamber 19. The contact bridge 16 is mounted floating in a section of bar 20 which communicates the opening and closing movements of the contacts 14,15,16 to it. The bar sections 20 of the three boxes 13 are secured by bars 21 coupled to a control mechanism, designated by the general reference 22. The mechanism 22 is disposed above the central pole of the circuit breaker and it is secured to the box 13 of this central pole by two spaced lateral flanges 23,24 which frame the mechanism 22. On the flanges 23,24 is articulated a control handle 25 which projects from the cover 12. On the flanges 23,24 is also articulated by an axis 26 , a crank 27 crossed by the bars 21 to control the rotation of the bar sections 20. A knee lever 28 connects the crank 27 to a hook 29, itself articulated by an axis 30, on the flanges 23,24. The end 31 of the hook 29, opposite the axis 30 carries a locking surface 32 capable of cooperating with a lock 33. The axis 34 of the toggle joint 28 is connected by a spring 35 to the handle 25. In the position closed from circuit breaker, shown in Figures 5 and 7, the spring 35 urges the toggle joint 28 in the extended position, tending to rotate the bar sections 20, counterclockwise, to maintain the contacts 14,15 , 16, in the closed position. A pivoting to the right in FIGS. 5 and 7 of the handle 25 displaces the line of action of the spring 35 causing the breaking of the toggle joint 28 and the rotation of the bar sections 20 in the clockwise direction, to open the contacts 14,15,16. The actuation of the latch 33 also causes the circuit breaker to open, by releasing the hook 29, which pivots anticlockwise towards the disarmed position, shown in FIG. 8, driving the crank 27 and the sections bar 20 to the open position of the contacts 14,15,16. The resetting of the mechanism 22 results from the displacement of the handle 25 towards the open position and it then suffices to pivot the handle in the opposite direction to close the circuit breaker. The lock 33 is controlled by a trip unit 36 associated or incorporated in the molded housing 10. Such a circuit breaker is described in the document FR-A-2,687,249 (published on 13.8.93) of the applicant, and the reader will advantageously refer at this request for further details on the operation and structure of this circuit breaker.

Le couvercle 12 comporte une plaque avant (non représentée), qui après enlèvement donne accès à quatre compartiments 37,38,39,40 ménagés dans le couvercle 12. Ces quatre compartiments 37-40 sont répartis sur une rangée de part et d'autre du mécanisme 22. Les quatre compartiments 37-40 ont une forme et une dimension identique pour recevoir chacun un bloc de contacts auxiliaires 41 standard. En se référant plus particulièrement aux figures 3 et 4, on voit que le bloc auxiliaire 41 présente des becs d'encliquetage 42, susceptibles de coopérer avec des parties conjuguées du compartiment 37-40, pour fixer par encliquetage le bloc 41, en matériau isolant, dans le compartiment correspondant. A l'intérieur du bloc 41 est montée à pivotement, une lame de contact 43, du type TUMBLER, qui coopère avec deux contacts fixes 44, pour constituer un contact inverseur. Le bloc 41 porte des bornes externes de connexion 45 et un poussoir 46 de commande de la lame de contact 43. Dans la position en saillie du poussoir 46, représentée à la figure 4, la lame de contact 43 coopère avec le contact fixe inférieur 44, tandis qu'en position enfoncée du poussoir 46, la lame de contact 43 coopère avec le contact fixe supérieur 44. Il est clair que le bloc auxiliaire 41 peut être agencé d'une manière différente et comporter un nombre supérieur ou inférieur de contacts 43,44, ainsi qu'un mode d'actionnement différent du poussoir 46.The cover 12 has a front plate (not shown), which after removal gives access to four compartments 37,38,39,40 formed in the cover 12. These four compartments 37-40 are distributed in a row on either side of the mechanism 22. The four compartments 37-40 have an identical shape and dimension to each receive a block of standard auxiliary contacts 41. Referring more particularly to FIGS. 3 and 4, it can be seen that the auxiliary block 41 has snap-on spouts 42, capable of cooperating with conjugated parts of compartment 37-40, for snap-fastening the block 41, made of insulating material , in the corresponding compartment. Inside the block 41 is pivotally mounted, a contact blade 43, of the TUMBLER type, which cooperates with two fixed contacts 44, to constitute a change-over contact. The block 41 carries external connection terminals 45 and a pusher 46 for controlling the contact blade 43. In the projecting position of the pusher 46, shown in FIG. 4, the contact blade 43 cooperates with the lower fixed contact 44 , while in the depressed position of the pusher 46, the contact blade 43 cooperates with the upper fixed contact 44. It is clear that the auxiliary unit 41 can be arranged in a different way and include a higher or lower number of contacts 43 , 44, as well as a different mode of actuation of the pusher 46.

Le bloc auxiliaire 41 est standard et il peut être mis en place dans l'un quelconque des compartiments 37-40, le poussoir 46 traversant un orifice 47 ménagé dans le fond du compartiment 37-40 et donnant accès à l'organe de commande correspondant 48,49,50. Les courses d'actionnement de tous ces organes de commande 48-50 sont identiques mais ces organes coopèrent avec des éléments différents du disjoncteur pour personnaliser le compartiment correspondant.The auxiliary unit 41 is standard and it can be installed in any one of the compartments 37-40, the pusher 46 passing through an orifice 47 formed in the bottom of the compartment 37-40 and giving access to the corresponding control member. 48.49.50. The actuating strokes of all these control members 48-50 are identical but these members cooperate with elements different from the circuit breaker to personalize the corresponding compartment.

Dans l'exemple illustré par les figures, le disjoncteur comporte deux compartiments 37,40 associés à la fonction de signalisation d'ouverture et de fermeture des contacts du disjoncteur. Un autre compartiment 38 assure la signalisation d'un déclenchement du disjoncteur et le quatrième compartiment 39 est affecté à la signalisation d'un déclenchement sur défaut électrique. Les organes de commande 48 des compartiments 37,40 de signalisation de la position des contacts sont, de la manière représentée aux figures 9 et 10, constitués par un coulisseau 51 intercalé entre deux boîtes unipolaires 13 et présentant une fourchette 52 qui embrasse une barre 21 de liaison des tronçons de barreaux 20. La figure 9 représente la position de la barre 21 lorsque les contacts 14,15,16 sont fermés, le coulisseau étant en position abaissée, sans action sur le poussoir 46 du bloc auxiliaire 41 qui reste en position de saillie. La figure 10 représente la position de la barre 21, lorsque les contacts 14,15,16 sont ouverts, le pivotement et le déplacement vers le haut de la barre 21 ayant déplacé le coulisseau 51 vers le haut, pour enfoncer le poussoir 46 et actionner la lame de contact 43 du bloc auxiliaire 41. Ce mode de commande par un coulisseau 51 est particulièrement simple et fiable, mais il est évident que l'information relative à la position des contacts peut être rélevée en un autre emplacement et peut être transmise au poussoir 46 par d'autres moyens.In the example illustrated by the figures, the circuit breaker comprises two compartments 37.40 associated with the function of signaling the opening and closing of the contacts of the circuit breaker. Another compartment 38 provides the signaling of a tripping of the circuit breaker and the fourth compartment 39 is assigned to the signaling of a tripping on an electrical fault. The control members 48 of the compartments 37, 40 for signaling the position of the contacts are, as shown in FIGS. 9 and 10, constituted by a slide 51 interposed between two single-pole boxes 13 and having a fork 52 which embraces a bar 21 connecting the sections of bars 20. FIG. 9 represents the position of the bar 21 when the contacts 14, 15, 16 are closed, the slide being in the lowered position, without action on the pusher 46 of the auxiliary block 41 which remains in position protrusion. FIG. 10 represents the position of the bar 21, when the contacts 14, 15, 16 are open, the pivoting and the upward movement of the bar 21 having moved the slide 51 upwards, to depress the pusher 46 and actuate the contact blade 43 of the auxiliary unit 41. This mode of control by a slide 51 is particularly simple and reliable, but it is obvious that the information relating to the position of the contacts can be raised in another location and can be transmitted to the pusher 46 by other means.

En se réfèrant plus particulièrement aux figures 6, 7, 8, on voit que l'organe de commande 49, du compartiment de signalisation de déclenchement 38 prélève l'information sur le crochet 29. A cet effet, un culbuteur 53 porte, d'une part l'organe de commande 49 et d'autre part une butée 54, maintenue en appui d'un bec 55 du crochet 29. Le réarmement du crochet 29, à, partir de la position désarmée, représentée à la figure 8, par pivotement de ce crochet, dans le sens des aiguilles d'une montre, provoque la rotation du culbuteur 53 dans le sens inverse des aiguilles d'une montre, et le déplacement vers le haut de l'organe de commande 49 qui agit sur le poussoir 46. Un déclenchement provoque un mouvement inverse du crochet 29 et du culbuteur 53 qui libère alors le poussoir 46. La position de la lame de contact 43 du bloc auxiliaire 41 associé, représente celle du crochet 29 et signale ainsi tout déclenchement du disjoncteur.Referring more particularly to Figures 6, 7, 8, it can be seen that the control member 49, of the trigger signaling compartment 38 takes the information from the hook 29. To this end, a rocker arm 53 carries, on the one hand the control member 49 and on the other hand a stop 54, held in abutment with a spout 55 of the hook 29. The resetting of the hook 29, from the disarmed position, represented in FIG. 8, by pivoting of this hook, clockwise, causes the rocker arm 53 to rotate anti-clockwise, and the upward movement of the control member 49 which acts on the pusher 46. A tripping causes a reverse movement of the hook 29 and the rocker arm 53 which then releases the pusher 46. The position of the contact blade 43 of the associated auxiliary block 41 represents that of the hook 29 and thus signals any tripping of the circuit breaker.

L'autre compartiment 39 signale un déclenchement sur défaut électrique, et à cet effet, son organe de commande 50 est associé à un relais 56 de commande de déclenchement. Le relais 56, illustré par la figure 11, est un électro-aimant logé dans un compartiment 57 du couvercle 12, en regard du compartiment 39, lequel relais actionne un équipage pivotant 58 ayant, d'une part une butée 59 d'actionnement du verrou 33 de déclenchement du disjoncteur, et d'autre part un levier constituant l'organe de commande 50. n convient de noter que la transmission au bloc auxiliaire 41 peut bien entendu être réalisé d'une manière différente et que le relais 56 peut être disposé ou agencé d'une manière différente.The other compartment 39 signals a trip on an electrical fault, and for this purpose, its control member 50 is associated with a trip control relay 56. The relay 56, illustrated in FIG. 11, is an electromagnet housed in a compartment 57 of the cover 12, opposite the compartment 39, which relay actuates a pivoting assembly 58 having, on the one hand a stop 59 for actuating the lock 33 for tripping the circuit breaker, and on the other hand a lever constituting the control member 50. It should be noted that the transmission to the auxiliary unit 41 can of course be carried out in a different way and that the relay 56 can be arranged or arranged in a different way.

La mise en oeuvre de l'invention ressort de l'exposé précédent. Le disjoncteur comporte quatre compartiments 37-40, dont deux, 37,40 ont pour fonction la signalisation de la position des contacts du disjoncteur, un autre compartiment 38 signalant la position déclenchée, et le quatrième compartiment 39 assurant la fonction de signalisation sur défaut électrique. Si l'installateur ou le distributeur veut disposer d'une signalisation de la position des contacts, il introduit dans le compartiment 37 ou 40, ou dans les deux si l'information doit être dédoublée, un bloc auxiliaire 41. La mise en place est simple, puisqu'il suffit d'encliqueter le bloc auxiliaire 41 et cette opération est effectuée sans aucun risque, les compartiments 37-40 étant fermés par rapport à la base 11 du disjoncteur, qui contient les parties actives.The implementation of the invention is apparent from the preceding description. The circuit breaker has four compartments 37-40, two of which, 37.40 have the function of signaling the position of the contacts of the circuit breaker, another compartment 38 signaling the tripped position, and the fourth compartment 39 providing the function of signaling on electrical fault. . If the installer or the distributor wants to have a signaling of the position of the contacts, he introduces into compartment 37 or 40, or both if the information has to be split, an auxiliary block 41. The installation is simple, since it suffices to snap on the auxiliary unit 41 and this operation is carried out without any risk, the compartments 37-40 being closed relative to the base 11 of the circuit breaker, which contains the active parts.

Selon les fonctions désirées, il introduit un bloc auxiliaire 41 dans l'un des autres compartiments 38 ou 39, ou s'il désire l'ensemble des fonctions, l'installateur introduit des blocs auxiliaires 41 dans chacun des compartiments 37-40. L'accès à ces compartiments 37-40, 57 est ensuite empêché par la mise en place de la plaque avant la fermeture du couvercle 12. L'enlèvement ultérieur d'un bloc auxiliaire 41 ou l'addition d'un tel bloc peut bien entendu être effectuée facilement après l'enlèvement de la plaque avant. Un même disjoncteur peut comporter un nombre supérieur ou inférieur de compartiments, lesquels peuvent être affectés à d'autres fonctions définies lors de la construction du disjoncteur. Le choix de la fonction résulte du choix du compartiment dans lequel le bloc auxiliaire standard 41 est mis en place. L'emplacement et la disposition de ces compartiments peuvent être différents et les liaisons des organes de commande de ces compartiments avec les éléments correspondants du disjoncteur peuvent être réalisés d'une manière différente, notamment électriquement ou par tout autre moyen.According to the desired functions, he introduces an auxiliary block 41 into one of the other compartments 38 or 39, or if he wishes all of the functions, the installer introduces auxiliary blocks 41 into each of the compartments 37-40. Access to these compartments 37-40, 57 is then prevented by the positioning of the plate before the closure of the cover 12. The subsequent removal of an auxiliary block 41 or the addition of such a block may well heard to be carried out easily after removal of the front plate. The same circuit breaker can have a greater or lesser number of compartments, which can be assigned to other functions defined during the construction of the circuit breaker. The choice of function results from the choice of the compartment in which the standard auxiliary unit 41 is put in place. The location and arrangement of these compartments may be different and the connections of the control members of these compartments with the corresponding elements of the circuit breaker may be produced in a different manner, in particular electrically or by any other means.
