Ranco G23-5253 Pressure Control

The Ranco G23-5253 Pressure Control is a heavy-duty single pole double throw (SPDT) high-pressure limit switch engineered for refrigeration compressor protection and head pressure management. Built for demanding commercial HVACR environments, this Type G control features a robust 150 to 450 PSI operating range and a manual reset mechanism. The manual reset functionality is a critical safety feature for field technicians, requiring physical intervention after a high-pressure trip to ensure the system is inspected before restarting. This unit comes equipped with a 60-inch capillary, providing versatile mounting options and vibration dampening for high-pressure lines. Whether you are performing a Ranco G23-5253 cross reference for an older PENN P70DA-1C or installing a new safety limit, this control delivers the precise setpoint reliability needed to prevent catastrophic compressor failure due to excessive head pressure.

• Enhanced System Safety: The manual reset ensures that high head pressure issues are addressed by a technician before the system resumes operation, protecting the refrigeration compressor from cycling on a fault.
• Versatile SPDT Switching: Features SPDT contacts (Single Pole Double Throw), allowing for simultaneous compressor cutout and alarm circuit activation.
• Broad Pressure Range: Adjustable from 150 PSI to 450 PSI, making it compatible with various high-pressure refrigerants and industrial machinery.
• Installation Flexibility: The 60-inch capillary and universal mounting design allow for flexible placement within the cabinet or remote mounting.

Can the Ranco G23-5253 be used for low-pressure applications?
No, this is specifically a high pressure limit control. For loss-of-charge protection or evaporator freeze-up monitoring, a Ranco G20 series or similar low-pressure control should be utilized.

How do I reset the G23-5253 after a trip?
The system pressure must drop approximately 40 PSIG below the cutout setpoint before the manual reset button can be successfully engaged to close the circuit.

What is the electrical rating for this pressure switch?
This control is typically rated for 120/240V AC applications with a 20A non-inductive load, making it suitable for standard commercial refrigeration and air conditioning power circuits.
