Allen-Bradley 100-A45N3 Contactor

The Allen-Bradley 100-A45N3 is a 3-pole starter contactor with a 110–120 VAC coil and a 45 A load rating, designed to reliably switch three-phase motors and other AC loads. This kit pairs the contactor with an 193-A1J2 overload relay for motor protection, allowing the control circuit to trip on overload conditions and protect the connected equipment. Rated to interrupt circuits up to 600 V across the contacts, it is suitable for use in industrial panels, conveyors, pumps, fans, and other automation applications where compact, mains-voltage motor control is required. With a compact footprint and standard coil voltage, the 100-A45N3 provides a straightforward solution for remote actuation of medium-current 3-phase motors at typical industrial frequencies, combining a rugged contactor with a reliable overload protection relay. Coil voltage 110–120 VAC makes it compatible with typical control circuits and PLC outputs, facilitating integration into standard automation architectures.
