Abstract
A circuit interrupter device includes line hot, line neutral, load hot, and load neutral terminals, a solid-state switch, internal short-circuit switch circuitry, and control circuitry. The solid-state switch is connected in an electrical path between the line hot and load hot terminals. The internal short-circuit switch circuitry comprises an internal short-circuit switch and a shunt resistor serially connected between the line hot and line neutral terminals. The control circuitry is configured to detect for an occurrence of a fault condition and in response to detecting the occurrence of a fault condition, the control circuitry is configured to drive the solid-state switch into a switched-off state, and activate the internal short-circuit switch to generate an internal short-circuit path between the line hot and line neutral terminals and allow short-circuit current to flow through the shunt resistor between the line hot terminal and the line neutral terminal of the circuit interrupter device.
