Schneider Electric 8501X040 Industrial Control Relay

Schneider Electric's Square D 8501X040 is a NEMA-style machine‑tool control relay designed for rugged industrial switching in control panels. The unit features a 110–120 VAC, 50/60 Hz coil and four normally open contacts, enabling four independent switching paths under coil actuation. It is rated for up to 10 A resistive load at 600 VAC, making it suitable for energizing motors, conveyors, and other machine-tool circuits from standard mains voltages. As part of the 8501X family, it supports modular assembly with either individual part configurations or pre‑assembled options to fit typical control‑panel architectures.
