Supco SLP4560 Low Pressure Switch | 45 Cut-Out / 60 Cut-In PSI, SPST

Description

Supco SLP4560 Low Pressure Switch

The Supco SLP4560 is a single-pole, single-throw (SPST) low pressure switch engineered to protect refrigeration and HVAC systems from dangerously low refrigerant pressures. Designed to open on pressure drop, this switch interrupts the circuit when system pressure falls to the cut-out setpoint, preventing compressor damage and ensuring safe system operation. When pressure recovers to the cut-in setpoint, the switch closes and restores normal operation.

Key Specifications

• Cut-Out (Open) Pressure: 45 PSI
• Cut-In (Close) Pressure: 60 PSI
• Switch Type: SPST (Single-Pole, Single-Throw)
• Action: Open on Pressure Drop
• Switch Function: Low Pressure Control
• Brand: Supco
• SKU: SLP4560

Features & Benefits

• Protects compressors from low refrigerant charge and loss of refrigerant conditions
• Opens circuit automatically when pressure drops to 45 PSI cut-out setpoint
• Resets and closes circuit when pressure recovers to 60 PSI cut-in setpoint
• SPST design provides simple, reliable switching for low pressure protection circuits
• Suitable for use in a wide range of refrigeration and air conditioning applications
• Durable construction from a trusted HVAC/R controls manufacturer

Application

The SLP4560 is ideal for use in residential, commercial, and light industrial refrigeration and air conditioning systems where low-side pressure monitoring is critical. It is commonly installed in compressor protection circuits to guard against low refrigerant levels, evaporator freeze-up, and other conditions that cause abnormal pressure drops.
