Copeland 940-C411-63 Relay

The Copeland 940-C411-63 is a professional-grade Current Relay Kit designed for precise motor starting control in commercial refrigeration systems. Engineered for high-reliability reciprocating compressors, this OEM relay-current kit features a 10.3 Amp pick-up and an 8.6 Amp drop-out rating, ensuring the start winding is efficiently disengaged once the motor reaches operational speed. This specific compressor start relay is essential for maintaining torque during high-load intervals, protecting the motor against overheating and premature failure in demanding HVACR environments.

Built for direct compatibility with Copeland refrigeration parts, the 940-C411-63 facilitates seamless integration with 040-C411-63 assemblies. Its rugged construction is tailored for technicians who require consistent performance in field replacements. By managing the electrical inrush current during the starting cycle, this current-sensing relay optimizes energy efficiency and stabilizes system pressure transitions. For contractors, utilizing an authentic OEM Copeland 940-C411-63 kit ensures that factory specifications for timing and current thresholds are met without the risks associated with generic aftermarket components.

• Precise Electrical Timing: Features a calibrated 10.3A pick-up and 8.6A drop-out threshold for accurate winding control.
• OEM Compatibility: Designed as a direct factory replacement for Copeland 040-C411-63 current relays.
• Enhanced Motor Protection: Prevents start-winding burnout by ensuring timely disconnection after motor ignition.
• High-Torque Support: Specifically tuned for reciprocating compressors requiring robust starting assistance under load.
• Heavy-Duty Construction: Built to withstand the high-cycle demands of commercial HVACR applications.

• What is the difference between a current relay and a potential relay? Current relays, like the 940-C411-63, operate based on the high inrush current of the start winding, whereas potential relays function based on the back-EMF generated by the motor.
• How do I verify if this relay kit fits my compressor? Reference the compressor's nameplate or model number; this kit is typically validated for specific Copeland reciprocating models using the 10.3/8.6 amp specifications.
• Can this kit be used with different refrigerants? Yes, as long as the compressor electrical specifications match, it is compatible with common refrigerants including R-134a and R-404a.
