Abstract
A control circuit for controlling an arc suppression circuit includes a serial communication link communicating a serial signal therethrough. The control circuit includes a microprocessor having a serial input communicating with the serial communication link. The microprocessor generates a control output signal in response to the serial signal. The control circuit further includes the arc suppression circuit having an electrical contact and operating in response to the control output signal to reduce an arc at the electrical contact.
