Copeland 971-C100-53 Overload

The Copeland 971-C100-53 Overload is a critical external protector designed for professional integration into Copeland compressor systems. Engineered for precision thermal overload protection, this industrial-grade relay prevents compressor failure by monitoring current draw and reacting to excessive heat or electrical spikes. It features a robust panel mount design, typically operating within a 10-15 Amp range at 250V AC, making it a standard requirement for maintaining HVACR system reliability in demanding commercial and industrial environments.

For service technicians and contractors, the 971-C100-53 provides a field-reliable solution for protecting industrial compressors from winding damage. Its primary function is to open the circuit before the motor reaches critical temperatures, effectively mitigating risks associated with locked rotor conditions or phase loss. This OEM Copeland part ensures exact electrical matching for compatible units, reducing call-backs and extending the operational life of the equipment in refrigeration and air conditioning applications.

• Thermal Protection: Rapidly detects and responds to overheating to safeguard motor windings.
• Precise Electrical Matching: Calibrated for specific Copeland compressor specifications to ensure accurate trip points.
• Industrial Durability: Built with high-grade materials to withstand the temperature fluctuations common in mechanical rooms.
• Minimal Down-Time: Features an easy-to-integrate panel mount configuration for fast field replacement.

Is the 971-C100-53 interchangeable with internal protectors?
No, this is an external overload relay. It is designed to be mounted externally on the compressor's electrical housing and should not be used to replace internal line break protectors.

What causes this overload to trip frequently?
Frequent tripping often indicates a mechanical issue within the compressor, such as a failing capacitor, non-condensables in the system, or excessive discharge pressure causing high amperage.

How do I verify if this part is compatible with my compressor?
You must match the overload part number precisely with your Copeland compressor model and serial number. Consult the manufacturer’s cross-reference guide to ensure the trip curve matches your motor's requirements.
