Square D 53705 X040V02 AC Control Relay is a Class 8501, Type X NEMA control relay with four normally open contacts rated for 10 A resistive at up to 600 VAC. It uses a 110/120 V AC coil (50/60 Hz) in the XO40V02 configuration, enabling reliable control of multiple load circuits from a single coil and making it suitable for machine-tool control and other AC control applications. This 120 V coil variant corresponds to Schneider Electric’s 8501XO40V02 family and is commonly used in industrial control panels to energize four separate circuits from a single control signal.
