Copeland 940-0001-55 Relay Kit

The Copeland 940-0001-55 Potential Relay Kit is a field-proven start component designed to provide reliable compressor motor starting in commercial refrigeration and high-demand HVAC applications. This OEM replacement part is the direct substitute for the legacy 040-0166-15 model, ensuring seamless HVAC system compatibility with residential and commercial units, including CF04K6E-PFV, CR30K6-PF, and CR34KF-PFV configurations. This 375V potential relay features a 3-screw terminal panel mount design, specifically engineered to manage the high pickup voltage (190-200V) and reliable dropout voltage (40-105V) required for heavy-duty cycling. By precisely controlling the start winding of the compressor, this Relay Kit prevents premature component wear and protects against electrical service faults. Field installation is streamlined with a standard 60 Hz frequency rating and a compact footprint that fits established mounting patterns. For technicians troubleshooting single-phase compressor starting issues, this kit provides the precise electrical switching necessary for peak operational efficiency.
