Schneider Electric 8501-DO-44-V110 AC Contactor

Schneider Electric 8501-DO-44-V110 is a NEMA-style control relay from the 8501 family designed to switch multiple AC circuits in industrial control panels. It features four normally open and four normally closed contacts, providing eight switching poles in a single compact package for interlocking, sequencing, and control of motors or auxiliary devices. The coil is rated for 110 VAC (50/60 Hz), making it compatible with standard automation control circuits. On the load side, the device is rated for up to 10 A resistive at up to 600 VAC, supporting direct switching of common control and signaling circuits in machine tools, conveyors, and other industrial equipment. As part of Schneider Electric’s Square D lineage, the 8501 family adheres to robust NEMA-style ratings and is designed for demanding environments where multiple switching functions are required from one relay. This 44 suffix configuration with a 110 V coil is suited for legacy control systems that need a multi-contact relay in a single unit, helping simplify wiring and improve reliability in industrial control panels.
