Abstract
A device for controlling an electrical current includes control circuitry, a micro electromechanical system (MEMS) switch in communication with the control circuitry, the MEMS switch responsive to the control circuitry to facilitate the interruption of an electrical current, a Hybrid Arcless Limiting Technology (HALT) arc suppression circuit disposed in electrical communication with the MEMS switch to receive a transfer of electrical energy from the MEMS switch in response to the MEMS switch changing state from closed to open, the HALT arc suppression circuit including a capacitive portion, and a variable resistance arranged in parallel electrical communication with the capacitive portion of the HALT arc suppression circuit, the variable resistance to dissipate a portion of the transferred electrical energy.
