The Furnas 21WE22AJ lighting-type magnetic contactor has four contacts: two normally open (NO) and two normally closed (NC), all controlled by a 24V coil at 60 Hz. It is designed for lighting-control circuits in electrical panels and automation systems, enabling switching of lighting loads with a low-voltage control signal while providing both NO and NC paths for logic or interlock configurations. This model, 21WE22AJ from Furnas, specifies a 24V coil and 60 Hz operation to support applications requiring a mixed NO/NC contact arrangement.
