Copeland 940-0150-51 Current Relay Hvac

Product Description

The COPELAND 940-0150-51 is a current relay designed as a direct-fit replacement for Copeland compressor and HVAC system applications. Current relays serve a critical function in single-phase compressor circuits, sensing the start winding current to engage and then release the start capacitor at the correct point in the motor start sequence. This part is engineered to meet or exceed original Copeland specifications, ensuring reliable compressor startup and run performance. Licensed HVAC technicians and refrigeration mechanics are the typical installers for this component in both residential and light commercial equipment.

The 940-0150-51 is suited for Copeland compressor and HVAC system applications including heating, cooling, and ventilation equipment. Typical install scenarios include compressor relay replacement during a no-start or hard-start diagnosis, or as part of a preventive maintenance rebuild on aging refrigeration or air conditioning equipment. The relay is built for plug-and-play fitment, reducing diagnostic time and minimizing system downtime during service calls.

Key Features

• Direct-fit replacement engineered for Copeland compressor and HVAC systems
• Meets or exceeds original Copeland engineering specifications for current relay performance
• Constructed for resistance to wear, corrosion, and thermal stress in demanding HVAC environments
• Plug-and-play design supports fast, accurate installation with minimal downtime
• Suitable for residential and commercial HVAC, heat pump, and air conditioning applications

Compatibility

Designed as a direct-fit replacement current relay compatible with Copeland heating, cooling, and ventilation systems. Consult Copeland documentation or cross-reference the existing relay part number to confirm fitment for your specific compressor model before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician or refrigeration mechanic. De-energize and lock out the equipment at the disconnect before removing the existing relay. Verify the replacement relay terminals match the original wiring configuration before making connections. Confirm system operation through a complete start cycle after installation to validate proper compressor startup behavior.
