Supco 44656 Potential Relay 30A 110-270VAC Single Phase

Product Description

The SUPCO 44656 is a single-phase potential relay rated for 30 amps and a wide voltage range of 110 to 270 volts AC. Potential relays are used in single-phase compressor motor starting circuits to disconnect the start capacitor from the circuit once the motor reaches operating speed. The 44656 is designed for reliable start-assist operation in compressor applications where motor inrush current must be managed efficiently. Licensed HVAC technicians and refrigeration service pros are the primary installers of this component.

This relay is suited for residential and light commercial refrigeration and air conditioning systems that use single-phase compressor motors requiring external start assistance. The broad voltage window of 110 to 270 volts AC makes it compatible with a range of compressor motor configurations without requiring a separate relay for each voltage class. It is commonly installed in hermetic and semi-hermetic compressor applications where a start capacitor is part of the motor circuit.

Key Features

• 30-amp contact rating supports high-inrush compressor motor starting loads
• Wide operating voltage range of 110 to 270 volts AC covers multiple system configurations
• Single-phase design for use with standard residential and light commercial compressor motors
• Potential relay design automatically disconnects the start capacitor once the motor reaches run speed
• Compact form factor typical of standard potential relay footprints for straightforward replacement

Compatibility

Designed as an OEM-style replacement potential relay for single-phase compressor motors operating within the 110 to 270 volt AC range in residential and light commercial HVAC and refrigeration equipment.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician. Disconnect and lock out all power to the unit before removing or installing any relay or capacitor components. Verify that the replacement relay coil pickup and dropout voltage ratings match the compressor motor specifications before energizing the system. Wiring connections should comply with NEC requirements for motor control circuits.
