Copeland 971-C100-19 Overload

The Copeland 971-C100-19 Overload is a critical internal motor protector designed for precise overcurrent prevention in HVACR systems. Built for 115-230 VAC applications at 50/60 Hz, this component monitors the current supply to the motor and interrupts power if it exceeds established thermal limits, preventing catastrophic winding failure. This specific compressor overload relay features an automatic reset mechanism, ensuring minimal system downtime by restoring power once the internal temperature stabilizes and the over-current condition is resolved.

When you are in the field dealing with a tripped circuit or a stalled compressor, using a genuine Copeland replacement part is non-negotiable for maintaining the integrity of the refrigeration cycle. Its compact design allows for seamless integration into various electrical panels and compressor housings, providing a reliable defense against motor overheating. This overload is engineered to handle the rigorous duty cycles of industrial machinery and commercial refrigeration units, offering consistent thermal overload protection where aftermarket alternatives often fail to meet the exact trip curve requirements of the original equipment.

• Dual-Voltage Compatibility: Operates efficiently across 115-230 VAC ranges, making it a versatile choice for a wide array of compressor models.
• Automatic Reset: Eliminates manual intervention after cooling, optimizing system uptime and reducing unnecessary service calls.
• Precision Calibration: Engineered with a specific trip current range to protect sensitive motor windings from persistent over-current scenarios.
• Robust Build: Constructed with high-grade materials to withstand the high-temperature environment of an active HVAC system.

• How do I confirm if the 971-C100-19 is the correct protector for my compressor? Verify the part number on your existing overload or consult the compressor nameplate data for specific protection requirements. This model is frequently used in high-efficiency Copeland scroll and reciprocating units.
• Does this overload require manual resetting? No, this unit features an automatic reset that triggers once the temperature drops below the safe threshold.
• What causes this part to trip frequently? Frequent tripping often indicates an underlying issue such as a failing start capacitor, high head pressure, or low line voltage.
