Copeland 940-0150-31 Relay-Current Kit
The Copeland 940-0150-31 Relay-Current Kit is a heavy-duty OEM replacement part engineered for precise compressor motor starting in residential and commercial HVACR refrigeration systems. Designed for high-inrush applications, this overcurrent relay utilizes a 13.35A pick-up and 11.35A drop-out rating to manage the starting circuit of fractional-horsepower compressors effectively. By monitoring the electrical draw of the run winding, the 940-0150-31 ensures the start winding is energized only during the initial torque phase, preventing thermal overload and protecting internal components from voltage fluctuation damage. This current sensing relay is a critical component for technicians performing compressor troubleshooting or routine HVAC preventive maintenance, offering a lightweight (0.14 lbs) yet robust solution for restoring system reliability. Its standardized design allows for seamless integration into existing control circuits, minimizing downtime and maintaining optimal equipment performance in demanding cooling environments.
Key Benefits:- Precise Current Regulation: Features a calibrated 13.35 Amp pick-up and 11.35 Amp drop-out for reliable starting circuit activation.
- Enhanced System Longevity: Protects sensitive compressor windings by preventing the starting components from remaining in the circuit longer than necessary.
- OEM Compatibility: Genuine Copeland refrigeration part ensures direct fitment and matches original factory specifications for HVAC electrical controls.
- Efficient Start Torque: Optimized for high-starting torque applications, ensuring compressors kick over even under challenging load conditions.
How do I test if the 940-0150-31 current relay is defective?
Technicians can verify the relay coil and contacts using an ohmmeter. In its upright position, the contacts should show infinite resistance (normally open). When inverted, the internal weight should cause the contacts to close, showing zero resistance. An open coil or stuck contacts indicate the need for a replacement.
Is this relay compatible with other compressor brands?
While designed specifically for Copeland compressors, current relays are matched based on the amperage draw of the run winding. Always verify the pick-up and drop-out ratings against the manufacturer’s data sheet for the specific motor being serviced.
What are the symptoms of a failing current relay kit?
Common signs include a compressor that "hums" but fails to start, frequent tripping of the thermal overload protector, or a compressor that starts but immediately shuts down due to the start winding remaining energized.
