Copeland 940-0172-04 Relay Kit
The Copeland 940-0172-04 Relay Kit is a critical solid-state current relay designed for precise HVAC compressor control. Engineered for 120V compressor motor applications, this OEM Copeland replacement part manages the electrical path to the start capacitor with high accuracy. When the compressor initiates, the relay detects the initial current draw and engages the start capacitor to provide the necessary torque for the motor drive. Once the motor reaches operational speed, the current-sensing technology within this 2.5-inch relay automatically disconnects the start circuit, allowing the compressor to run efficiently on the run capacitor. This systematic switching is vital for preventing electrical faults and ensuring the long-term reliability of the system's control architecture. For technicians, using a genuine 940-0172-04 kit ensures seamless integration into existing Copeland residential or commercial setups, maintaining factory-spec performance and protection against premature compressor wear or failure.
- Precise Current Sensing: Ensures the start capacitor is engaged only as long as necessary, protecting the motor windings.
- OEM Compatibility: Specifically calibrated for Copeland compressors to match original performance specifications.
- Solid-State Durability: Provides reliable switching under varying operational loads and temperatures.
- Optimized Start Torque: Facilitates rapid compressor startup, reducing the duration of high-amp inrush current.
Common Questions
Is the 940-0172-04 a universal HVAC relay?
No, this is a specific current relay kit designed primarily for 120V Copeland compressors. It is essential to verify your specific compressor model or the original part number before installation to ensure electrical compatibility.
What are the symptoms of a failing current relay?
Common signs include the compressor "humming" but failing to start, frequent tripping of the circuit breaker during startup, or the motor overheating due to the start circuit remaining engaged too long.
Does this kit include the mounting hardware?
This is a standard service kit intended for direct replacement; technicians should refer to the unit's original wiring diagram to confirm lead connections and mounting orientation.
