Supco SHP375265 High Pressure Switch, 375 PSI Cut-Out, 265 PSI Cut-In, SPST

Description

The Supco SHP375265 is a single-pole, single-throw (SPST) high pressure switch engineered to protect refrigeration and air conditioning systems from damaging over-pressure conditions. Designed to open on a pressure rise, this switch automatically interrupts the circuit when system pressure reaches the cut-out threshold, then resets as pressure drops back to the cut-in point — providing dependable, automatic protection for compressors and refrigerant circuits.

Key Specifications

• Cut-Out (Open) Pressure: 375 PSI
• Cut-In (Close) Pressure: 265 PSI
• Switch Action: Opens on pressure rise (high-side protection)
• Switch Type: SPST (Single-Pole, Single-Throw)
• Brand: Supco
• SKU / Part Number: SHP375265

How It Works

The SHP375265 monitors high-side refrigerant pressure. When pressure climbs to 375 PSI, the switch opens, de-energizing the compressor or control circuit to prevent equipment damage. Once pressure falls back to 265 PSI, the switch closes and restores normal operation — providing automatic, self-resetting protection without manual intervention.

Applications

• Residential and commercial air conditioning systems
• Refrigeration equipment compressor protection
• Heat pump high-side pressure safety circuits
• OEM and field replacement installations requiring SPST high pressure switching
