CA 2223452

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 transfer these to buttons on switches. Depressing these switches depending on the position of the mechanical assembly makes and breaks circuits that are in communication 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 réguler 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 présente plusieurs positions correspondant aux divers états d'un coupe circuit. Des leviers convertissent les mouvements d'amplitudes relativement importantes du mécanisme en mouvements de faible amplitude et les transferts aux boutons sur les commutateurs. L'enfoncement de ces commutateurs en fonction de la position de l'ensemble mécanique établit et coupe des circuits qui communiquent avec un site éloigné. L'invention porte sur une carte de circuit conçue spécialement pour contenir et situer les commutateurs et les leviers et fournir des trajectoires pouvant supporter des courants importants. L'invention porte en outre sur une fiche terminale comportant une languette destinée à être tirée pour donner accès à une fiche terminale autrement inaccessible. L'invention porte en dernier lieu sur une base à double fonction, servant à la fois de boîtier et d'élément d'espacement.
