Allen-Bradley HB474 Contactor Coil

The Allen-Bradley HB474 Contactor Coil is a genuine replacement AC coil for HB-series contactors, delivering 240 V at 60 Hz or 220 V at 50 Hz to energize the magnetic circuit and pull in the main contacts that switch motors and other heavy loads in industrial control panels. Designed for industrial motor-control applications, the HB474 coil enables reliable operation of equipment such as conveyors, pumps, fans, and processing lines by providing the control power to the associated contactor as part of the Rockwell Automation ecosystem. Being a Rockwell/Allen-Bradley component, it is intended for use in compatible HB-series contactor assemblies with matching coil voltage and frequency, ensuring consistent pickup characteristics and long-term durability in harsh factory environments. To ensure proper performance, confirm that your control supply is 240 VAC at 60 Hz or 220 VAC at 50 Hz, and replace worn or failed coils with HB474 to restore original control behavior.
