Copeland 940-C016-03 Relay Kit

The Copeland 940-C016-03 Relay Kit is a critical OEM replacement component designed to restore proper starting torque in single-phase refrigeration systems. This current sensing relay is engineered specifically for Copeland hermetic compressors, ensuring the start winding is accurately disconnected once the motor reaches sufficient RPM. Built to handle the high inrush current typical of commercial HVACR applications, the 940-C016-03 facilitates a precise electrical cycle, preventing compressor overheating and premature component failure. This kit is essential for service technicians addressing compressor hard start issues or intermittent cycling in reach-in coolers and small condensing units. Utilizing genuine Copeland motor start components maintains the integrity of the original electrical design and ensures compatibility with matched start capacitors. Verification of the LRA (Locked Rotor Amps) and terminal configuration is recommended for seamless field installation on legacy and current production models.

• Precise Cut-out Calibration: Engineered to disconnect start windings at the optimal voltage to protect the motor windings.
• High Current Rating: Designed to withstand heavy-duty cycles common in commercial refrigeration environments.
• Plug-and-Play Compatibility: Standard terminal layout ensures a direct fit for Copeland condensing unit electrical boxes.
• Enhanced System Reliability: Reduces electrical stress during the startup phase, extending the lifecycle of the compressor.

What are the symptoms of a failing Copeland 940-C016-03 current relay?
Technicians typically observe the compressor failing to start while drawing high amperage, or the compressor cycling on the thermal overload protector. If the relay contacts weld shut or fail to close, the start winding will not engage or disengage correctly, leading to motor failure.

Can this relay be used on non-Copeland compressors?
While current relays operate on universal principles, the 940-C016-03 is calibrated for specific Copeland compressor motor profiles. Using this relay on a mismatched motor can result in improper cut-out timing, potentially damaging the start winding or capacitor.

Does this kit include the start capacitor?
This kit focuses on the current induction relay. It is professional practice to inspect the start capacitor for proper microfarad output and replace it if it shows signs of leakage or deviates from its rated capacitance.
