Allen-Bradley 71A83 Relay Coil Assembly 220-240V AC

Allen-Bradley 71A83 is a Size 1 coil assembly for the Bulletin 700 Series K contactors and motor starters, designed for 220-240V AC operation (50/60 Hz). This replacement coil energizes the magnetic circuit to close the contactor contacts in motor control circuits, enabling reliable switching of motors and other heavy loads in industrial panels. It is specified for use with Series K, Size 1 devices and supports non-reversing, reversing, multi-speed, and combination configurations within the 700 line, including compatibility with models such as 702-BOA, 702L-BOA, 709-BOA, 705-B, 707-B, 712-B, 713-B, and 715-B. The 71A83 coil preserves the original mounting pattern and electrical interface, allowing straightforward substitution for worn or failed coils without modifying surrounding hardware. This coil’s 220-240V AC rating aligns with common North American and international power standards, ensuring compatibility in legacy Allen-Bradley motor control panels that rely on the 700-series coil family, and making it suitable for replacement in a wide range of industrial automation applications.
