Allen-Bradley 70A27 is a magnetic coil (contactor/starter coil) designed to energize an Allen-Bradley contactor used to switch heavy loads in motor-control applications. Identified as 70A27 in the Allen-Bradley coil family, this part is sold as a replacement coil for 70-series contactors and is distributed under the Rockwell Automation brand. In practice, the coil is mounted on a compatible Allen-Bradley contactor and energized to close the contactor contacts, enabling control of motors and other high-current devices. For proper operation, confirm compatibility with your specific contactor model and verify the coil voltage and wiring requirements before installation.
