Schneider Electric 8501-CO-3AK AC Control Relay Coil

Schneider Electric's Square D 8501-CO-3AK is a 24V AC coil for the 8501 CO-3 AC control relay within the Square D 8501 family of NEMA-style open-frame relays. This coil energizes the relay's magnetic armature to actuate the attached contact cartridge, enabling control of line-voltage loads in industrial automation and panel-mounted control circuits. The AK suffix denotes the coil variant for this CO-3 configuration, and the coil voltage is specified as 24 VAC. Typical uses include machine-control applications, motor and conveyor line control, and other industrial control scenarios where 8501 relays are employed to manage loads through a replaceable cartridge system.
