Square D 8501CO6V04 Power Relay

Square D by Schneider Electric 8501CO6V04 Power Relay, Type C, is a through-panel, open-power relay built to switch high-power loads in industrial control panels. It uses a 277 VAC coil to energize a single Form A SPST (normally open) contact rated for 30 A at up to 300 VAC resistive loads and supports up to 2.0 HP motors, with operation specified for 50/60 Hz environments. The device employs four terminals and is designed for panel mounting in open enclosures, providing a compact, rugged solution for HVAC equipment control and motor-start circuits where a high-current, line-voltage switch is required. With a 277 VAC coil and a 30 A contact rating, it enables reliable disconnection and switching of powerful loads in control panels. Dimensions measure 2.5 in W x 2.43 in H x 2.25 in D, helping ensure compatibility with standard panel cutouts.
