Sylvania A13U031 Electromechanical Contactor Coil

Sylvania A13U031 electromechanical contactor coil is a NEMA Size 1 control coil rated for 120 VAC (110–120 V, 60 Hz) and is identified with coil TB159-1. At 120 V, the coil typically draws about 27 VA, making it suitable for energizing the associated 27 A, 200–575 VAC three‑phase contactor in industrial motor control. This coil is designed to be used with Sylvania/NEMA Size 1 starters in control panels to switch three‑phase motors such as conveyors, pumps, fans, and compressors, where compact size and reliable actuation are important. When paired with the corresponding T13U031/A13U031 family contactor, it provides the control side of a motor starter capable of handling up to 27 A on the load side while operating from standard 120 V control circuitry.
