Abstract: A system including an arc flash sensor that detects an arc flash event and an arc flash mitigation device in communication with the sensor. The mitigation device includes a path of least resistance having a path input and a path output. The arc flash sensor is located downstream the output. The mitigation device includes an electro-mechanical switch between the input and the output and an actuator. The mitigation device also includes a bypass power switch device that includes a solid-state circuit interrupter and that conduct current between the input and the output in response to an open-circuit condition of the switch. A system controller is provided to generate a trigger to activate the actuator to generate the open-circuit condition of the switch, which causes the power switch device to interrupt a fault current associated with a fault event in response to detection of the arc flash event.

Abstract: A device includes an electro-mechanical switching device having an open-circuit and closed-circuit conditions and a path of least resistance having a path input and a path output with the switching device between the input and the output. The device includes a bypass power switch device that comprises a solid-state circuit interrupter and that is configured to conduct current between the input and the output in response to an open-circuit condition of the switching device. The device includes a current sensor that is connected to the output and configured to detect a fault current event. The device includes an actuator that is coupled to the switching device and a controller that is configured to generate a trigger signal to activate the actuator to cause the open-circuit condition of the switching device and to interrupt the fault current event by the power switch device, based on the detected fault current event.
