1. A system comprising:
an arc flash sensor configured to detect an arc flash event; and
an arc flash mitigation device in communication with the arc flash sensor, the arc flash mitigation device comprising:
a path of least resistance having a path input and a path output, the path output being configured to serve as an input to a load, wherein the arc flash sensor is located downstream of the path output;
an actuator;
an electro-mechanical switch between the path input and the path output;
a bypass power switch device that comprises a solid-state circuit interrupter and that is configured to conduct current between the path input and the path output in response to an open-circuit condition of the electro-mechanical switch; and
a system controller configured to generate a trigger signal to activate the actuator to generate the open-circuit condition of the electro-mechanical switch, which causes the bypass power switch device to interrupt a fault current associated with a fault event, in response to detection of the arc flash event by the arc flash sensor.
