Copeland 940-0001-59 Relay Kit

The Copeland 940-0001-59 Potential Relay Kit is a heavy-duty electrical component engineered for precise single-phase compressor motor starting. This technical kit features a high-performance 420V potential relay designed to handle the high inrush currents typical of industrial refrigeration and commercial HVAC applications. By monitoring the voltage across the start winding, the 940-0001-59 ensures that the start capacitor is disconnected at the exact moment the motor reaches optimal speed, protecting both the winding and the start capacitor from thermal stress. Built to OEM specifications, this kit is essential for maintaining compressor operational efficiency in demanding environments. Field-proven and compact, the Copeland motor start relay integrates seamlessly into existing control circuits, providing a reliable solution for technicians troubleshooting erratic startup cycles or failed starting components in Copeland Scroll or Copelametic systems.

• Optimized Motor Starting: Precisely manages start winding disengagement to prevent component overheating.
• Industrial-Grade Rating: Rated for 420V applications, suitable for high-demand commercial refrigeration.
• Enhanced Component Protection: Extends the life of the compressor by ensuring clean, consistent startup cycles.
• OEM Compatibility: Exact replacement kit for Copeland systems, ensuring proper fit and terminal alignment.
• Durable Construction: Engineered to withstand the rigors of industrial mechanical rooms and frequent cycling.

Is this relay compatible with 230V systems?
This specific kit is rated for 420V operation. Always verify your system's voltage and the pickup/dropout specifications of your existing potential relay before installation.

What are the signs of a failing potential relay?
Common indicators include the compressor humming without starting, blown start capacitors, or intermittent starting issues under high load conditions.

Can this be used for non-Copeland compressors?
While functionally similar to other relays, this relay kit is designed to meet specific Copeland technical parameters. Check your wiring diagram to confirm terminal logic and voltage requirements.
