Square D by Schneider Electric 8501X040V02 Control Relay

Square D by Schneider Electric 8501X040V02 is a Type X, NEMA-style AC control relay with four normally open contacts (4 Form A) mounted on a four-pole base for flexible expansion. It uses a 110/120 VAC coil operating at 50/60 Hz and delivers a 10 A resistive (up to 600 VAC) contact rating, making it suitable for control of motors, pumps, and other industrial loads in automation panels. The relay features plug-in contact cartridges for easy maintenance and conversion, along with self-lifting pressure wire connectors that simplify field wiring and improve connection reliability. As part of the 8501 Type X family, the 8501X040V02 can be paired with additional decks, coils, or latching options to tailor the contact configuration to the application, while preserving straight-through wiring inside the base. This modular design supports quick replacement and customization in harsh industrial environments, where rugged construction and long life matter. Typical uses include machine control circuits, conveyors, and control panels in manufacturing and process environments, where four independent NO contacts are required and a 120 V AC control coil is available.
