Square D by Schneider Electric 8501X040 Relay

Square D by Schneider Electric 8501X040 Relay is a NEMA‑style industrial control relay from the 8501 Type X family, delivering four normally open contacts that switch four separate circuits from a single coil. Built for rugged machine‑tool and general automation applications, this relay offers robust construction and modular wiring to simplify installation, maintenance, and replacement in control panels. It is commonly employed to control motors, conveyors, fans, heaters, and other loads in industrial automation where coordinated, four‑circuit switching is required. The 8501X040 variant is part of the 8501X lineup, and coil voltage as well as exact electrical ratings vary by the specific coil option chosen; consult the official Schneider Electric product page or datasheet for your selected coil to confirm compatibility with your control system and supply voltage. The 8501X family is widely used in panel assemblies and machine controls, enabling reliable operation with quick field replacement when a relay needs servicing. By design, these relays support standard Square D accessories within the same product family to maintain consistent performance across control panels.
