Allen-Bradley 4A86 Contactor

The Allen-Bradley 4A86 Contactor is a coil-operated motor starter from Rockwell Automation, designed to remotely switch power to AC motors and other inductive loads in industrial control panels. It uses a 120V AC coil rated for 60 Hz operation, so a control signal energizes the coil, closing the main contacts to supply the connected load and de-energizing to break the circuit. The 4A86 designation identifies this specific contactor within Allen-Bradley’s catalog, placing it among trusted factory automation components used to implement reliable motor-start sequences in equipment like pumps, conveyors, fans, and compressors. This device is built to perform as a fundamental control element in industrial automation, enabling simple, remote control of motors via standard control logic and switches, and it reflects Allen-Bradley’s long-standing emphasis on robust, serviceable motor-control hardware.
