Allen-Bradley 84AB86 U is the 120V AC operating coil for Allen-Bradley 700-N AC control relays, designed to energize a contactor or starter in motor-control and automation panels. The coil is specified for 120 VAC at 60 Hz, with an 110 VAC/50 Hz variant available in the same family, and is intended for CNTR or STR configurations in the 700-N relay lineup. It is used to energize 700-N relays in industrial control circuits that drive contactors or starters in motor-control applications. The U designation identifies this 120V variant, making it the appropriate choice when a 120V coil is specified for a control panel upgrade or replacement in systems that use 700-N relays.
