ABSTRACT:
A circuit interrupting device is disclosed that includes a first conductor, a second conductor, a switch between the first conductor and the second conductor wherein the switch is disposed to selectively connect and disconnect the first conductor and the second conductor, a circuit interrupter disposed to generate a circuit interrupting actuation signal, a solenoid coil and plunger assembly disposed to open the switch wherein the solenoid coil and plunger assembly is actuatable by the circuit interrupting actuation signal wherein movement of the plunger causes the switch to open, and a test assembly that is configured to enable a test of the circuit interrupter initiating at least a partial movement of the plunger in a test direction, from a pre-test configuration to a post-test configuration, without opening the switch.
