Copeland 985-0110-01 Compressor Protector

The Copeland 985-0110-01 Compressor Protector is a high-reliability 240V solid-state motor protection module engineered for heavy-duty commercial and industrial applications. Designed to integrate seamlessly with Copeland Discus compressors, this module serves as a critical defense against motor overheating, locked rotor conditions, and voltage imbalances. By utilizing advanced diagnostics technology, the 985-0110-01 continuously monitors sensor resistance and electrical data to identify abnormal operating conditions before they lead to catastrophic equipment failure.

A veteran HVACR technician knows that protecting the compressor's windings is non-negotiable for system longevity. This compressor terminal module features a normally closed (NC) contact interface, allowing it to be wired directly into the contactor control circuit. In the event of an internal overload trip or a detected phase loss, the module interrupts the coil voltage, effectively shutting down the compressor until conditions stabilize. Its robust design is optimized for environments with significant vibration and temperature fluctuations, ensuring consistent refrigeration system protection without the nuisance trips common in inferior generic parts.

• Advanced Thermal Monitoring: Provides precise response to compressor discharge temperature and internal winding heat to prevent insulation breakdown.
• Streamlined Troubleshooting: Integrated LED status indicators allow field technicians to quickly diagnose fault codes and reduce downtime.
• Plug-and-Play Compatibility: Designed specifically for 240V Copeland semi-hermetic compressors, ensuring matched electrical characteristics and mounting.
• System-Wide Integration: Works in tandem with oil pressure safety switches and CoreSense™ technology for comprehensive HVACR equipment protection.

• What does the module protect against? It primarily monitors motor winding thermistors to prevent damage from over-current, low voltage, and thermal overload.
• Can this module replace older 120V protectors? No, this unit is rated specifically for 240V control circuits. Always verify the transformer secondary voltage before installation.
• How do I reset a lockout? Most lockouts require cycling the 24V or 240V control power once the underlying thermal or electrical fault has been cleared and the motor has cooled.
