Allen-Bradley 73A86 Industrial Solid State Relay

Allen-Bradley 73A86 is an operating coil for the Allen-Bradley Bulletin 700-Series motor starters, sized as Size 3. This coil is designed for use with 700-series contactors in 2- to 3-pole configurations and is available with 120 V AC operation at 60 Hz or 110 V AC operation at 50 Hz, depending on the specific coil variant. When energized, the coil activates the starter to close the main contacts, enabling motor control in industrial automation applications such as conveyors, pumps, and fans. The 73A86 coil is compatible with multiple Bulletin 700 Series contactors, including models in the 702-DOD/702L-DOD, 709-DOD, 705-D, 707-D, 712-D, 713-D, and 715-D families, all of which use the Series K, Size 3 coil platform. Installation follows standard mounting practices for Bulletin 700 line starters; coil-only replacements can be swapped within the same size and voltage class without rewiring the control circuit. Because coil current and inrush characteristics vary with supply frequency and the specific contactor arrangement, consult the factory specification sheets for exact electrical parameters for your installation.
