Copeland 940-C411-72 Relay Kit

Optimizing compressor startup and reliability, the Copeland 940-C411-72 Current Relay Kit is a field-proven OEM replacement part designed for high-integrity refrigeration and HVAC compressor systems. As a critical motor starting relay, this kit monitors the electrical draw during the initial induction phase, ensuring the start winding is disengaged at the precise moment to prevent thermal overload and winding damage. This Copeland relay kit is engineered for seamless integration with compatible refrigeration compressors, maintaining strict adherence to factory-specified electrical tolerances. Built for durability in demanding industrial environments, the current relay features a compact form factor for rapid installation in existing control boxes. By utilizing genuine Copeland parts, technicians ensure optimal performance and long-term system stability, effectively reducing service calls related to compressor start-up issues and intermittent cycling.

• Precise Current Monitoring: Reliably manages the transition between start and run cycles to protect sensitive compressor windings.
• OEM Compatibility: Exact factory replacement for 940-C411-72, ensuring electrical and physical fitment without field modifications.
• Enhanced System Reliability: Designed to withstand high-cycle applications in commercial refrigeration and process cooling.
• Simplified Installation: Compact current relay kit design fits easily into standard electrical housings for efficient field service.

Is this relay compatible with non-Copeland compressors?
This kit is engineered specifically for Copeland refrigeration compressors. Always cross-reference your specific model number with the manufacturer’s technical data to verify a match.

What are the symptoms of a failing current relay?
Common signs include the compressor hum but fail to start, frequent tripping of the thermal overload, or the start winding remaining energized too long, which can lead to motor burnout.

Can I use a potential relay instead of this current relay?
No. Current relays and potential relays operate on different electrical principles. You must use the 940-C411-72 if the system is designed for a current-sensing start component.
