Allen-Bradley 72A27 Relay Coil 24V AC 60 Hz

Allen-Bradley 72A27 Relay Coil is a 24V AC, 60 Hz coil intended for use with Allen-Bradley size-2 contactors and starters. This replacement coil energizes the associated contactor to switch power to loads in industrial control circuits, a common arrangement in motor control panels, conveyors, pumps, and other automation equipment. The coil is rated for 24 volts AC at 60 Hz, matching standard North American control-signal specifications, and is identified by the 72A27 part number for compatibility with specific Allen-Bradley contactor assemblies. Manufactured by Allen-Bradley (Rockwell Automation), these coils are designed as replacements for worn or damaged coils within Allen-Bradley starters, enabling installation with the contactor’s coil terminals and mounting footprint. The size-2 coil form factor fits the corresponding mounting interface and electrical characteristics, allowing straightforward installation in existing control circuits.
