Square D 8501CO22V20 General Purpose Relay Dpdt 10 Va

Product Description

The SQUARE D 8501CO22V20 is a double-pole double-throw (DPDT) electromechanical general purpose relay rated at 10 VA with a 120 VAC coil operating at 50/60 Hz. Contact ratings are 10 amps at 110 volts and 4 amps at 220 volts. Screw clamp terminals provide a secure, vibration-resistant connection without the need for ferrules or ring terminals. This relay is suited for control panel integration, machine control circuits, and low-voltage switching applications where a reliable electromechanical switching element is required. Licensed electricians and industrial controls technicians are the primary installers.

This relay fits into general-purpose relay socket and panel-mount applications across residential, commercial, and light industrial control systems. It is commonly used in HVAC control panels, motor starter auxiliary circuits, and sequencing logic where a DPDT switching configuration is needed. The 120 VAC coil voltage makes it compatible with standard North American control-circuit voltages. At 2.5 inches wide, 2.4 inches high, and 3.2 inches deep, it fits standard DIN-rail or panel-mount enclosures designed for this relay footprint.

Key Features

• DPDT contact form supports two independent switched circuits from a single coil
• 10 VA coil power rating with 120 VAC at 50/60 Hz operation
• 10 amp contact rating at 110 volts, 4 amps at 220 volts
• Screw clamp terminals for tool-tightened, pull-out-resistant wiring
• CSA, UL Listed, IEC 60947-4-1, and RoHS compliant
• Compact footprint at 2.5 x 2.4 x 3.2 inches for panel-space efficiency

Compatibility

Designed as an OEM-style general purpose relay for use in control panels and switching circuits requiring a DPDT electromechanical relay with a 120 VAC coil and screw clamp termination.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the control circuit before removing or inserting the relay. Torque screw clamp terminals to the enclosure or relay socket manufacturer specification using an appropriate flat-blade screwdriver. Confirm coil voltage matches the control circuit supply before energizing.
