  • Circuit breaker solid state trip unit incorporating trip indicating circuit
    Patent number: 4068283
    Abstract: A separate electronic switch controls energization of each of a plurality of parallel connected electromagnetic targets. An additional electronic switch controls energization of a circuit breaker trip solenoid. The individual trigger circuits for each target switch are common with the trigger circuit for the trip solenoid switch, such that a trigger signal to any one of the target switches is also applied to the solenoid switch to achieve concurrent, but independent energization of the associated target and the trip solenoid.
