Copeland 971-0561-48 Overload Protector

Professional-grade Copeland 971-0561-48 Overload Protector kits are essential for preventing catastrophic compressor motor failure in high-demand HVAC and refrigeration environments. As an experienced tech knows, maintaining a reliable thermal and electrical barrier is non-negotiable for system longevity. This genuine Copeland part is engineered to monitor both current draw and winding temperature, providing a precise break in the electrical circuit when thresholds are exceeded. By interrupting power before excessive heat can warp windings or degrade insulation, this overload relay mitigates the risks associated with voltage fluctuations and mechanical binding.

Designed for seamless integration into various hermetic compressor systems, the 971-0561-48 features a compact footprint (2.75" x 3.55" x 2.25") that fits easily into standard terminal boxes. Its robust construction ensures sensitivity to amperage spikes while remaining durable under harsh industrial conditions. Whether you are performing a compressor troubleshooting routine or a preventative overload protector replacement, this kit provides the technical precision required for residential and commercial motor protection. Using this OEM Copeland kit ensures your repairs meet factory specifications for reliability and performance.

• Precision Thermal Sensing: Instantly detects high internal temperatures to prevent compressor overheating.
• Current Overload Mitigation: Protects against locked rotor amps (LRA) and electrical surges.
• Universal Motor Compatibility: Specified for a range of Copeland compressor models, including AFE17 and RST40 series.
• Automatic Reset Logic: Restores the circuit once safe operating temperatures are reached, reducing unnecessary service calls.
• Compact Form Factor: Simplifies HVAC part installation in tight terminal housings.

Common Questions:

How do I test if the Copeland 971-0561-48 is faulty?
Disconnect the power and use a multimeter to check for continuity across the terminals. If the protector is cool but shows an open circuit, it has likely failed and requires replacement.

What causes this overload protector to trip frequently?
Frequent tripping is often a symptom of low refrigerant charge, a failing start capacitor, or high ambient temperatures causing the compressor to work outside its design parameters.

Is this part compatible with three-phase compressors?
While many Copeland scroll compressors use internal overload protection, the 971-0561-48 is specifically designed for systems requiring an external kit. Always verify your specific model's wiring diagram before installation.
