Copeland 971-0554-22 Overload

The Copeland 971-0554-22 Overload is a precision-engineered external overload protector kit designed to provide mission-critical compressor motor protection for high-demand HVACR systems. Built for heavy-duty commercial and industrial cooling applications, this overload relay monitors electrical current in real-time, acting as a failsafe against excessive amp draw, phase loss, and thermal runaway. As an OEM Copeland replacement part, it ensures seamless integration with original equipment specifications, maintaining the factory-standard protection levels required to prevent catastrophic stator failure or winding damage.

For service contractors troubleshooting a tripping unit, the Copeland 971-0554-22 offers a reliable trip response tailored to the specific operational curves of compatible Copeland compressors. This protective device helps mitigate the risks associated with dirty condenser coils, refrigerant imbalances, or failing start components that can lead to motor overheating. Its robust construction is designed to withstand the high-vibration environments of a mechanical room, providing stable electrical overload protection and ensuring that the compressor operates strictly within its designated safety parameters to avoid premature mechanical wear.

• Genuine OEM quality ensures exact technical compatibility and reliable trip-point accuracy for Copeland systems.
• Advanced thermal protection prevents winding burnout by disconnecting the motor from the power supply during abnormal current conditions.
• Direct replacement overload design simplifies field installation, reducing system downtime during critical repairs.
• Versatile application in refrigeration compressors and commercial HVAC equipment across a wide range of voltages.
• Engineered to handle current loads typically ranging from 20 to 60 amps depending on the system configuration.

Is the Copeland 971-0554-22 an internal or external overload?
This model is an external overload protector, typically mounted where it can be easily tested and replaced by a technician, unlike inherent internal protectors embedded in the motor windings.

What causes this overload relay to trip frequently?
Common triggers include high head pressure due to restricted airflow, low refrigerant charge causing the motor to run hot, or a failing run capacitor increasing the amp draw beyond safe limits.

Can I use this overload for non-Copeland compressors?
While designed specifically for Copeland compressor motor protection, compatibility is based on the motor's amperage and trip curve. Always verify the cross-reference data and technical specifications before use.
