Allen-Bradley 71A86 Operating Coil for Industrial 120V AC Relay Unit

Allen-Bradley 71A86 is an operating magnetic coil for Bulletin 700 Series motor starters and contactors, sized for Series K, Size 1 frames, which energizes the associated contacts when the control voltage is applied to enable motor control in industrial panels. The coil is specified for 120 V AC operation at 60 Hz, with compatibility to 110 V AC at 50 Hz in compatible installations, and it is designed to fit the Series K frame within the 700-line family, supporting non-reversing, reversing, multi-speed, and combination starter arrangements such as 702-BOD, 709-BOD, and related 705-, 707-, 712-, 713-, and 715-B models. As part of Allen-Bradley’s motor-control coil lineup, the 71A86 provides a compact, reliable actuation option for industrial equipment, and replacements are commonly sourced when refurbishing legacy systems that rely on Bulletin 700 components.
