ABSTRACT:
A replaceable circuit breaker module has a housing for supporting and enclosing elements of the module, a circuit breaker mounted in the housing in a manner that an action of installing the module connects the breaker to bridge an incoming and an outgoing conductor, and monitoring circuitry for monitoring characteristics of the circuit breaker, the monitoring circuitry mounted in the housing and having a first connector element for engaging a mating connector element in the action of installing the module. The module is characterized in that action of withdrawing the circuit breaker module also withdraws the monitoring circuitry. Sensors in the monitoring circuitry may include sensors for monitoring one or more of breaker presence, on/off state of the breaker, and voltage provided to the breaker.
