Square D 8501 XO80 Industrial Control Relay

Square D by Schneider Electric 8501 XO80 Type X NEMA control relay is a rugged, modular industrial relay designed for machine-tool control circuits, delivering eight contact poles in a single housing. The XO80 family supports coil voltages that vary by model: 110–120 VAC (V02) and 220–240 VAC (V03), both rated for 50/60 Hz operation. A representative V03 version lists 8 normally open contacts with a coil rated for 220–240 VAC and a resistive load rating of 10 A at up to 600 VAC. The 8501 family emphasizes replaceable, convertible contacts and modular construction, with options to expand pole count via adders and to configure different contact arrangements to suit wiring needs.
