The Square D 31041 relay coil is an AC coil designed to energize a compatible Square D control relay when supplied with 110V or 120V alternating current. Identified by part number 31041, this coil is part of Square D’s relay component lineup used in electrical control panels and other control circuits that require a Square D coil. When the 110–120V control signal energizes the coil, it actuates the relay and causes its contacts to switch, enabling control of connected loads in the control circuitry. This coil is used in applications where a Square D relay is required to interface the control circuit with the load side of the system.
