The Dayton Electric 5X157A is a three‑phase motor starter in a NEMA Size 3 frame designed to control a three‑phase motor from a 110–120 VAC control circuit. This 3‑pole unit uses a 110–120 VAC coil to energize its contacts, serving as the primary switching element in motor control panels for industrial equipment. It is suitable for integration into industrial motor control panels and equipment that require compact, standard‑frame three‑pole motor control of a three‑phase motor.
