Ranco G23-5052 Control

For veteran HVACR technicians requiring reliable high-head pressure protection, the Ranco G23-5052 Control is a purpose-built electromechanical solution for commercial refrigeration and air conditioning systems. This single-pole double-throw (SPDT) pressure switch features a 150 to 450 PSI cut-out range, providing critical equipment safety by monitoring discharge pressures. The unit is field-adjustable with a 50 to 125 PSI differential, allowing contractors to fine-tune the 375/290 PSI setting for precise open/close cycles based on specific system load requirements. Designed for high-limit applications, the G23-5052 utilizes a 60-inch capillary tube for flexible remote mounting and is compatible with common refrigerants including R-22, R-134a, and R-404A. Its automatic reset logic ensures minimal downtime while maintaining a failsafe against overpressure conditions. Built for durability in demanding environments, this pressure controller offers a snap-action switch design and a compact footprint that integrates easily into existing control panels or compressor housings.

• Flexible Installation: The 60-inch capillary allows for remote pressure sensing and versatile mounting away from direct compressor vibration.
• Adjustable Differential: Features a wide 50 to 125 PSI differential range to prevent short-cycling and maintain stable head pressure.
• SPDT Switching: High-performance single-pole double-throw switch facilitates simplified wiring for both high-pressure cut-out and alarm circuit integration.
• Reliable Protection: Specifically engineered for high head pressure protection, safeguarding compressors from damage due to restricted condenser airflow or fan failure.

What is the maximum pressure limit for the G23-5052?
This control has a high limit of 450 PSI and an adjustable range starting at 150 PSI to accommodate various refrigeration cycle requirements.

Does this unit require manual intervention after a pressure trip?
No, the G23-5052 is an automatic reset model; once the pressure drops back within the differential setting, the switch will automatically close the circuit.

Can this be used for low-pressure sensing?
The G23 series is primarily designed for high-side protection. For low-side or loss-of-charge protection, a Ranco G20 series or similar suction-sensing control is recommended.
