ABSTRACT:
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 communication with a remote site. 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. A dual-function base, which serves both as an enclosure and as a spacer.
