Supco SLP2045 Pressure Switch
The Supco SLP2045 Pressure Switch is a high-precision, encapsulated low pressure control engineered for standard HVAC and refrigeration system protection. This single-pole single-throw (SPST) switch is designed to open on pressure drop at 20 PSI, preventing compressor operation during low-charge conditions or evaporator freeze-ups, and features an automatic reset that closes at 45 PSI. For efficient field installation, it includes a 1/4" SAE 45° female flare fitting with an integrated valve core depressor and 18-inch 18 AWG lead wires.
Constructed with a hermetically sealed, snap-acting stainless steel sensor, the SLP2045 provides excellent set point repeatability and stability across extreme temperature ranges. This direct mount switch is compatible with CFC, HCFC, and HFC refrigerants, including modern A2L blends. Its durable design is rated for 100,000 cycles at full load, supporting 24/120/240 VAC applications. Technicians often utilize this model to replace Mars 43345 or Robertshaw 3100003 units in commercial refrigeration and residential split-system air conditioning.
Key Benefits for HVACR Systems:- Enhanced System Reliability: Automatically cuts power to the compressor contactor when pressure falls below 20 PSI to prevent mechanical failure.
- Wide Refrigerant Range: Tested for compatibility with R-22, R-410A, and newer mildly flammable A2L refrigerants.
- Durable Construction: Features an encapsulated body and stainless steel internals to resist vibration and environmental ingress.
- Simple Installation: The compact direct-mount design with a built-in core depressor allows for mounting without losing system charge.
- Universal Voltage Support: Rated for use in various control circuits from 24V up to 240VAC.
- What are the electrical ratings for this switch? The SLP2045 supports up to 5.8 FLA at 120VAC and 2.9 FLA at 240VAC.
- Can this be used with DC voltage? Yes, it is rated for 6VDC, 12VDC, and 36VDC applications.
- Is this switch adjustable? No, this is a fixed, non-adjustable safety control factory-set for 20/45 PSI operation.
- What is the maximum pressure this unit can handle? It features a high burst pressure rating of 5000 PSI to handle system surges.
