CP7 series AC Motor Starter is suitable for circuits with AC voltage up to 690V and current up to 80A. It provides protection against overload, phase loss, and short circuit, and is used for infrequent starting of three-phase squirrel cage asynchronous motors. It can also protect distribution lines for occasional load switching and serve as an isolator.
