Allen-Bradley 70A288 is a size-0 AC operating coil for Allen-Bradley contactors, rated for 440–480 VAC and suitable for 50/60 Hz control circuits. When energized with control power in the 440/480 V range, the coil actuates the contactor to switch the connected load, making it a critical component in motor control and other high-power line applications. This coil is identified by the 70A288 part number and is intended for use in industrial control panels that require a size-0 coil with a 440/480 V AC, 50/60 Hz rating.
