Schneider Electric 8501XO40V02 AC Relay Coil 110-120V

Schneider Electric's Square D 8501XO40V02 is a NEMA Type X control relay designed for machine-tool applications, delivering four normally open contacts in a single coil-controlled package (4 Form A / 4NO). It uses a 110/120 VAC coil rated for 50/60 Hz, with a coil power of 23 VA, allowing direct operation from standard mains in many industrial settings. The four NO contacts provide a resistive-load rating up to 10 A at 600 VAC, enabling multiple loads or signaling paths to be switched from one relay coil. Wiring employs screw-clamp terminals for secure, vibration-tolerant connections, and the compact body measures roughly 2.23 in wide, 3.95 in deep, and 3.50 in high, making it suitable for panel or machine installations where space is at a premium. This V02 variant is part of Schneider Electric’s 8501X family of relays, a lineage commonly used in automation and control panels for reliable duty in demanding environments. Ideal for sequencing, interlocks, or multi-circuit control in machine-tool or automation control panels, the 8501XO40V02 provides a straightforward, single-coil solution to switch up to four independent circuits at 110/120 VAC and 50/60 Hz while maintaining robust 600 VAC load rating and broad compatibility with Schneider Electric components.
