1. A system, comprising:
a controller configured to receive an output of a sensor indicating an operating condition of a solid state switching element, wherein the solid state switching element is operable in an arc-free manner; and
wherein the controller is configured to output control signals to the solid state switching element based on the received output of the sensor to operate the solid state switching element to share a current load with at least one mechanical switching device to limit arcing energy to a level below that which presents an ignition concern in an explosive environment.
