Allen-Bradley 73A86 Operating Contactor Coil 120V 60Hz

Allen-Bradley 73A86 Operating Contactor Coil is a size-3 magnetic coil for the Bulletin 700 Series contactors, specifically Series K, intended for 2- to 3-pole configurations. It supports dual-voltage operation, with nominal coil voltage of 120 V at 60 Hz and 110 V at 50 Hz, enabling use on common North American AC power systems. The coil’s purpose is to energize the contactor armature to close the main contacts in motor starters and related control circuits, delivering reliable actuator performance in industrial automation applications. This 73A86 coil is designed to mate with compatible 700-line contactors within the Series K, Size 3 family, providing straightforward integration for control of AC motors in 2- to 3-pole starter assemblies.
