CA 2223453

The present invention provides an accessory module for monitoring and controlling the status of a circuit breaker. The accessory module attaches to the side of a circuit breaker and has a mechanism similar to the mechanism in a circuit breaker. The mechanism has multiple positions that correspond to multiple states of a circuit breaker. Actuators transform relatively large- scale motions of the mechanism into small-scale motions and transfers these to buttons on switches. Depressing these switches depending on the position of the mechanical assembly makes and breaks circuits that are in communcication with a remote site. The invention provides a circuit board designed specifically to hold and locate the switches and actuators and provide tracings that can withstand high currents. The invention further provides a terminal plug having a pull tab which can be grasped to remove an otherwise inaccessible terminal plug. The invention further provides a dual-function base, which serves both as an enclosure and as a spacer.

Module accessoire permettant de contrôler et commander l'état d'un coupe-circuit. Ce module accessoire se fixe sur le côté d'un coupe-circuit et comporte un mécanisme analogue au mécanisme d'un coupe-circuit. Ce mécanisme prévoit plusieurs positions qui correspondent aux différents états d'un coupe-circuit. Des leviers convertissent les mouvements d'amplitude relativement importante du mécanisme en mouvements de faible amplitude et les transfère aux boutons sur les commutateurs. L'enfoncement de ces commutateurs en fonction de la position de l'ensemble mécanique établit ou coupe des circuits qui sont en communication sur un site éloigné. L'invention porte sur une plaquette de circuit conçue spécialement pour abriter et placer les commutateurs et les leviers et fournir des trajectoires pouvant supporter des courants importants. L'invention porte également sur une fiche terminale comportant une languette devant être tirée pour être enlevée et donner ainsi accès à une fiche terminale autrement inaccessible. L'invention porte enfin sur une base à double fonction, servant à la fois de boîtier et d'élément d'espacement.
