Supco SLP1032 Low Pressure Switch, 10 PSI Cut-Out, 32 PSI Cut-In, R410A, SPST

Description

The Supco SLP1032 is a precision-engineered low pressure switch designed to protect R410A refrigeration and air conditioning systems from dangerously low refrigerant pressure conditions. With a cut-out (open) pressure of 10 PSI and a cut-in (close) pressure of 32 PSI, this switch automatically interrupts the circuit when system pressure drops below the safe threshold — helping prevent compressor damage and costly system failures.

Built with a Single-Pole Single-Throw (SPST) configuration and an open-on-pressure-drop action, the SLP1032 provides straightforward, reliable low-side protection. It is specifically rated for R410A refrigerant applications, making it an ideal replacement or upgrade component for modern residential and light commercial HVAC systems.

Key Features

• Cut-Out (Open) Pressure: 10 PSI — opens circuit on low pressure drop
• Cut-In (Close) Pressure: 32 PSI — closes circuit when pressure recovers to safe level
• Switch Type: SPST (Single-Pole Single-Throw)
• Action: Open on Pressure Drop — protects system during refrigerant loss events
• Refrigerant Compatibility: Rated for R410A applications
• Designed for low-side pressure monitoring in refrigeration and A/C systems

Application

The SLP1032 is suited for use in residential and light commercial split-system air conditioners, heat pumps, and refrigeration equipment utilizing R410A refrigerant. It monitors low-side system pressure and opens the control circuit when pressure falls below 10 PSI, signaling a potential refrigerant shortage or system fault before compressor damage can occur.
