Allen-Bradley 74A86 Operating Coil For Size 4 2-3P AC Contactor Coil

Allen-Bradley 74A86 is a magnetic operating coil engineered as a direct-replacement for NEMA size 4, 2- to 3-pole contactors in the Bulletin 700, Series K line. This AC coil energizes the corresponding motor starter to switch power to connected loads and is specified for either 120V at 60 Hz or 110V at 50 Hz operation, making it compatible with standard control voltages used on legacy drives and panels. Designed to fit size 4, 2-3 pole configurations, the 74A86 provides the magnetizing force required for reliable actuation when paired with compatible Bulletin 700 Series K contactors, including common 702-series devices. In aftermarket listings and distributor catalogs, you will find 74A86 marketed as a replacement coil for Allen-Bradley NEMA size 4, 2-3 pole start/stop devices. Typical coil current at the 120V variant runs around 0.54 A, reflecting a compact draw in line with other size-4, 2-3 pole coils in the Series K family. Whether updating legacy equipment or stocking spare parts for maintenance, the 74A86 coil delivers compatibility with the Series K motor starter family and the broader Bulletin 700 contactor ecosystem.
