Abstract
An integral circuit interrupter characterized by an assemblage of interconnected electrical units including a circuit breaker, a thermal-magnetic overcurrent detector, an electromagnetic actuator, and a modular sensor; the circuit breaker comprising first and second separable contacts and a releasable lever for releasing the first contact to an open position when the detector trips the lever in response to a first predetermined current condition; the electromagnetic actuator for moving the second contact to an open position; the modular sensor for monitoring current flow and for actuating only the electromagnetic actuator in response to a second predetermined current condition; and the electromagnetic actuator being operable from a remotely controlled source.
