Overview
The Westinghouse A200M2CACD is a Size 2 motor starter that delivers dependable three-phase motor control for industrial machinery and production equipment. This unit pairs the A200M2CAC main contactor with a BA23A thermal overload relay, providing both electromagnetic switching and motor protection in a compact NEMA 2 enclosure. Rated at 45 amps and suitable for motors up to 25 HP at 460/575 volts, the A200M2CACD has been a workhorse in facilities and manufacturing environments for decades. Though discontinued by Westinghouse, used units remain highly sought by maintenance teams and system integrators seeking reliable replacements.
