ELECTRICAL SWITCHING APPARATUS WITH EMBEDDED ARC FAULT PROTECTION AND SYSTEM EMPLOYING SAME
摘要:
An electrical switching apparatus, such as a subminiature circuit breaker, includes a housing assembly, separable contacts, an operating mechanism having an actuator device and a latching assembly, a first trip device for tripping open the separable contacts in response to an overcurrent condition, and a second trip device for tripping open the separable contacts in response to an arc fault, a ground fault or a remotely transmitted signal. The subminiature circuit breaker includes a reset solenoid and a trip solenoid. The resent solenoid is coupled to the actuator device, and includes a coil operable to electrically reset the separable contacts. The trip solenoid is coupled to the latching assembly, and includes a coil operable to move the catch lever, thereby electrically tripping open the separable contacts.
