Description
The Copeland 063541 XB-1019SW651B is a precision-engineered power assembly designed for reliable performance in low-temperature refrigeration applications. Built for use with R404A refrigerant, this power assembly delivers accurate thermostatic control across a wide application temperature range, making it a trusted solution for commercial refrigeration systems.
Key Features
- Designed for use with R404A refrigerant
- Equalizer type: 1/4″ SAE (Flare) external equalizer connection
- 5-foot (5 ft) capillary tube length for flexible installation
- Application temperature range: -50°F to +25°F — ideal for low-temperature and medium-temperature refrigeration
- Maximum Operating Pressure (MOP): 65 PSI — protects compressor from high suction pressure conditions
- Capscrews included for complete, ready-to-install assembly
Application
This Copeland power assembly is engineered for use in commercial refrigeration environments where precise temperature control and compressor protection are critical. The 65 PSI MOP rating prevents compressor overload during pull-down or high ambient conditions, while the broad -50°F to +25°F operating range makes it suitable for walk-in coolers, reach-in cases, and other low- to medium-temperature refrigeration systems using R404A refrigerant.
