Allen-Bradley 70A86 is a magnetic operating coil for NEMA Size 0 motor starters and contactors, rated for 120V AC at 60 Hz (with 110V at 50 Hz specified for compatible configurations). It energizes the coil of Bulletin 700/702/705/709 Size 0 contactors to switch the main contacts in motor-control circuits, enabling a controlled start and stop of industrial loads. Part of the Series K family, the 70A86 is commonly paired with 120V/60Hz control power, and data sheets note the 110V/50Hz variant for use in regions with that supply. Designed for installation in standard control panels, this compact coil fits where Size 0 coils are specified.
