Allen-Bradley 84AB01 Magnetic Coil

The Allen-Bradley 84AB01 Magnetic Coil is an AC operating coil used to energize Allen-Bradley contactors or starters in industrial control panels, converting an applied voltage into a magnetic field that closes or opens the relay contacts to control motors and loads. It is specified for a nominal 110 V alternating current and supports 50/60 Hz operation, with a practical voltage window of 95–110 VAC at 50 Hz to accommodate common power systems across installations, ensuring reliable operation in mixed-frequency environments. The official catalog number is 84AB01, and distributor listings commonly note it as a coil for use with the 700-N AC control relay family, aligning with Allen-Bradley's broader line of control components and providing a predictable fit with compatible relays. Typical applications include motor control circuits, conveyors, and automated packaging lines where a 110 VAC coil is required to actuate a control relay, with the coil designed to mate with compatible Allen-Bradley contactors or starters in panel assemblies.
