Supco SHP350250 Pressure Switch
The Supco SHP350250 Pressure Switch is an essential field-ready component for managing high-side pressure in professional refrigeration and air conditioning systems. This high-pressure control is engineered with a SPST (Single Pole Single Throw) configuration that is designed to Open on Pressure Rise, providing a critical safety cutoff when system pressures reach 350 PSI. The switch features an automatic 250 PSI Cut-In, ensuring efficient condenser fan cycling and protection for commercial HFC, HCFC, and CFC systems. This unit is built for direct mounting with a 1/4" SAE female flare fitting and includes a built-in valve core depressor for streamlined installation. As a direct industry cross-reference for Mars 5679, this hermetically sealed sensor utilizes a snap-acting stainless steel mechanism to maintain set point stability across 100,000 cycles. With a rated voltage of up to 240V and 18-inch 18 AWG leads, it provides versatile compatibility for technicians troubleshooting HVAC pressure control issues.
Key Benefits
- Universal Refrigerant Compatibility: Developed for use with standard refrigerants and modern A2L blends, making it a versatile tool for the modern technician's truck.
- Rugged Hermetic Seal: The stainless steel sensor is encapsulated to withstand harsh ambient and fluid temperatures found in rooftop units and reach-in coolers.
- Verified Interoperability: Replaces common OEM and aftermarket parts including Mars 5679 and various Robertshaw and Johnson Controls models.
- Simplified Installation: The lightweight, compact housing and 1/4" SAE connection allow for direct mounting in tight compressor compartments without extra brackets.
Common Questions
Does this switch require a manual reset?
No, the Supco SHP350250 features an automatic reset once the high-side pressure drops to the 250 PSI cut-in point.
Can this be used for condenser fan cycling?
Yes, this switch is frequently utilized as a condenser fan cycling control to maintain head pressure by opening the circuit on pressure rise.
What is the maximum electrical load for this switch?
It is rated for 6 RLA and 36 LRA at 120/240 VAC, providing heavy-duty performance for standard HVACR equipment motors and contactors.
