Abstract
A circuit breaker accessory assembly, such as a shunt trip solenoid, is affixed to an insulative mounting member which is interchangeably mounted in place of a conventional interphase barrier within the breaker molded case. The trip solenoid plunger is operatively coupled with the breaker common trip bar, while the actuator for a normally closed switch wired in the solenoid energization circuit is positionally mounted for actuation by movement of a breaker contact arm to its open circuit position, thereby opening the switch.
