Copeland 940-0001-53 Relay
The Copeland 940-0001-53 Relay is a high-performance potential start relay engineered for precise motor starting torque in HVACR refrigeration systems. This heavy-duty compressor start relay is designed specifically for Copeland Scroll compressors, including hermetic models such as the AFT26C1(E)-CFV and AFT29C1(E)-CFV. With a voltage rating featuring a 260/280V pick-up and a 50/110V drop-out, this component provides reliable electrical disconnection once the motor reaches operational speed, preventing winding damage and ensuring localized thermal protection. The unit is rated for a 375V contact capacity and operates on standard 60 Hz frequency. As an OEM replacement part, it handles up to 35A of current, making it a critical technical specification for contractors maintaining commercial or residential air conditioning units. Utilizing this genuine Copeland 940-0001-53 ensures optimal starting characteristics and protects the long-term integrity of the compressorās internal components in demanding cooling applications.
Key Benefits- Precise Electrical Timing: Features a calibrated pick-up voltage of 260/280V to provide consistent starting torque for high-pressure Copeland Scroll applications.
- High-Current Durability: Rated for up to 35A current at 375V, accommodating the heavy inrush requirements of industrial HVACR compressors.
- OEM Compatibility: Exact replacement for Copeland 940-0001-53 and 3ARR3KC10A5 potential relays, ensuring seamless integration with existing wiring harnesses.
- Optimized Motor Protection: Rapidly disconnects the start capacitor circuit upon reaching speed, effectively preventing motor overload and winding burnout.
What compressors are compatible with the Copeland 940-0001-53 relay?
This potential relay is primarily designed for Copeland Scroll compressors and specific hermetic models like the AFT26C1 and AFT29C1 series used in air conditioning and refrigeration.
How do I troubleshoot a failing 940-0001-53 start relay?
Technicians should check for continuity across the 1-2 contacts and verify the pick-up voltage. If the compressor hums but fails to start or the start capacitor stays in the circuit too long, the relay likely requires replacement.
Can I use this relay for both residential and commercial units?
Yes, provided the electrical specifications match. It is rated for 375V and 35A, making it suitable for a wide range of single-phase motors requiring a start relay.
