Square D 8501CDO6V51 General Purpose Relay 2HP Spst 12VDC

Product Description

The SQUARE D 8501CDO6V51 is an electromechanical general purpose relay rated for 2 HP and 10 VA, designed for industrial and commercial control circuit applications. Built with a screw clamp terminal configuration and a SPST contact form, it operates on a 12 VDC coil. The relay handles up to 10 amps at 600 volts and 40 amps at 277 VAC, making it suitable for a range of switching duties. It meets CSA, UL, IEC 60947-4-1, and RoHS standards. Licensed electricians and controls technicians typically specify this relay for machine control panels, HVAC control boards, and automation systems.

This relay fits standard general purpose relay applications in both residential and light commercial environments. It is commonly installed in relay panels, motor control centers, and equipment control circuits where a single-pole single-throw switching function is required. Its screw clamp terminals provide a secure, tool-assisted termination suitable for environments with vibration or thermal cycling. Verify coil voltage and contact rating against the application schematic before installation.

Key Features

• SPST contact form for single-pole single-throw switching
• 12 VDC coil voltage for low-voltage control circuit compatibility
• 10 amp rating at 600 volts and 40 amp rating at 277 VAC
• Screw clamp terminals for secure, vibration-resistant wire termination
• Meets UL, CSA, IEC 60947-4-1, and RoHS compliance requirements
• Compact form factor suitable for relay panels and DIN rail enclosures

Compatibility

Designed as an OEM-style replacement for general purpose electromechanical relays used in industrial and commercial control panel applications requiring a 12 VDC SPST screw clamp relay.

Installation Notes

Installation should be performed by a licensed electrician following applicable NEC requirements. De-energize and lock out the control circuit before handling or replacing the relay. Screw clamp terminals require a small flat-blade screwdriver for proper conductor seating. Confirm coil voltage, contact form, and current rating match the circuit design before energizing.
