PURPOSE: A receptacle is provided to detect arc default and test the arc default. CONSTITUTION: A trip switch and a reset switch are installed in the bottom of an insulation case(105). A cover(110) is installed on an upper portion of the insulation case(105). The first and second test buttons(121,122) are allocated in the insulation case(105) to be capable of being risen and fallen. Upper ends of the first and second test buttons(121,122) are exposed through the cover(110), and lower ends of the first and second test buttons(121,122) are adjacently allocated to the trip switch. The first spring provides a recovery force to the first and second test buttons(121,122). A reset button is allocated in the insulation case(105) to be capable of being risen and fallen. An upper end of the reset button is exposed through the cover(110), and a lower end of the reset button is adjacently allocated to the reset switch. A locking device interlocks to the rising and falling operation of the first and second test buttons(121,122), and selectively locks the reset button.

Abstract:
Resettable circuit interrupting devices (10) having a reset lockout and an optional independent trip mechanism (50, 52, 54) are provided. The reset lockout prevents the resetting of the circuit breaker if the fault protection is non-operational or if an open neutral condition exists, and the trip mechanism operates independently of the fault protection operations.
