Allen-Bradley 70A86 Size 0 Manual Motor Starter

Allen-Bradley 70A86 is the Series K operating coil for NEMA Size 0 manual motor starters in Allen-Bradley Bulletin 700-series motor-control equipment. It energizes the starter’s magnetic coil to switch a small motor on and off in control circuits. This coil is rated for 120 V AC at 60 Hz or 110 V AC at 50 Hz, making it compatible with 50/60 Hz control voltages across regions. It is designed for use with Bulletin 709, 70A, and 70D Size 0 contactors, delivering a compact Size 0 form factor suitable for panel-mounted motor-control schemes. The 70A86 part number identifies the coil assembly and is commonly used as a replacement part for aging Allen-Bradley equipment. When paired with a compatible Size 0 manual motor starter, this coil enables reliable actuation in motor-control applications such as fans, pumps, conveyors, and other small-motor drives in industrial environments. Typically stocked by distributors for service and maintenance of aging Allen-Bradley motor-control panels.
