Square D 8501CO6V04 General Purpose Relay 2 Hp Spst

Product Description

The SQUARE D 8501CO6V04 is an electromechanical general purpose relay rated at 2 HP and 10 VA, designed for industrial and commercial control circuit applications. It features a single-pole single-throw (SPST) contact form with screw clamp terminal connections for secure, vibration-resistant wiring. The relay handles 10 amps at 600 volts and 40 amps at 277 VAC, operating on a 277 VAC coil at 50/60 Hz. Licensed electricians and industrial controls technicians install this type of relay in panel boards, motor control centers, and machine control enclosures where reliable switching of load circuits is required.

The 8501CO6V04 suits residential, commercial, and light industrial control applications where a compact, screw-clamp relay is specified. Typical installations include HVAC control panels, motor starters, lighting contactors, and general automation panels. Its SPST contact configuration makes it appropriate for single-circuit load switching where one normally open or normally closed contact path is needed. The compact body fits standard DIN-rail or panel-mount enclosures without requiring significant space allocation.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the panel or control circuit before removing or installing the relay. Verify coil voltage and contact ratings match the application before energizing. Do not exceed the rated current or voltage on either the coil or load contacts.
