1. A motor starter comprising:
micro-electromechanical system switching circuitry; and
at least a first over-current protection circuitry connected in a parallel circuit with the micro-electromechanical system switching circuitry, the first over-current protection circuitry configured to momentarily form an electrically conductive path in response to a first switching event of the micro-electromechanical system switching circuitry, said electrically conductive path in a parallel circuit with the micro-electromechanical system switching circuitry for suppressing arc formation between contacts of the micro-electromechanical system switching circuitry during the first switching event.
