Product Overview
The Copeland CRNQ-050E-TFD-556 is a hermetic reciprocating compressor designed for air-conditioning and compatible high-temperature refrigeration duties. Its sealed construction combines the motor and compression mechanism in one housing, helping reduce external leakage points and simplifying installation in packaged HVAC equipment.
This TFD configuration uses a thermally protected three-phase motor and is rated for both 50 Hz and 60 Hz supplies. The electrical rating is 380/420 V at 50 Hz and 380/460 V at 60 Hz, with a locked-rotor current of 65.0 A.
For replacement projects, use the complete CRNQ-050E-TFD-556 model rather than CRNQ-050E alone. Refrigerant, lubricant, cooling duty, pipe connections, mounting dimensions and the original equipment specification all need to match the existing system.

Compatibility and Selection Notice
Do not select a compressor from nominal horsepower or body shape alone. Confirm the complete CRNQ-050E-TFD-556 code, refrigerant, oil, voltage, phase, frequency, design conditions, line connections and mounting arrangement against the old unit and equipment documentation.
Published performance for another CRNQ-050E bill of material is not automatically the rating of this exact supplied configuration. Cooling capacity changes with evaporating temperature, condensing temperature, superheat, subcooling and power supply.
