Square D 8501CDO6V53 General Purpose Power Relay

Square D 8501CDO6V53 is a Type C general‑purpose power relay designed to switch AC loads in industrial controls. It provides a 30 A resistive rating at up to 300 VAC with SPST‑NO (1 Form A) contacts, making it suitable for single‑phase motor starters, heaters, lighting circuits, and other moderate load applications in control panels. The device uses a 24 V DC coil, enabling straightforward integration with standard low‑voltage control circuits while maintaining electrical isolation between the control and power circuits. In a compact 4‑pin open‑frame package, it is typically installed in electrical panels or equipment enclosures to simplify wiring and mounting for dependable on/off control. As a Square D general‑purpose relay, this model is designed for reliable operation in intermittent duty and light industrial environments, providing a single normally open path that closes when the coil is energised. When selecting a replacement or upgrade, this 8501C family member is commonly chosen for straightforward control schemes requiring a robust, familiar form factor from a trusted manufacturer.
