Abstract

A circuit interrupter (11,11',11'') includes a sensor (12,12') structured to output a sensor signal, a control unit (16) structured to receive an external control signal, the control unit including: a communication interface (20) structured to receive the external control signal, and a waveform generator (22) structured to generate a waveform equivalent to the sensor signal in response to the external control, and a signal processing circuit (14) structured to receive and process the sensor signal or the generated waveform and to output the processed sensor signal or generated waveform to the control unit.

Description

technical field [0001] The disclosed concept relates generally to circuit interrupters, and more particularly to circuit interrupters including test modules. Background technique [0002] Electrical switching apparatus includes, for example, circuit switching devices, circuit interrupters such as circuit breakers, network protectors, contactors, motor starters, motor controllers, and other load controllers. Electrical switching apparatus, such as circuit interrupters and especially circuit breakers, are well known in the art. [0003] Circuit interrupters, such as but not limited to circuit breakers, are used to protect electrical circuits from damage due to an overcurrent condition (such as an overload condition, a short circuit) or another fault condition (such as an arc fault or a ground fault). Molded case circuit breakers typically include a pair of separable contacts per phase. The separable contacts may be operated manually by a handle provided on the exterior of th...
