Supco SHP400280 High Pressure Switch, 400 PSI Cut-Out / 280 PSI Cut-In, SPST

Description

The Supco SHP400280 is a single-pole, single-throw (SPST) high pressure switch engineered to protect refrigeration and air conditioning systems from dangerous over-pressure conditions. Designed to open on pressure rise, this switch automatically interrupts the circuit when system pressure reaches the 400 PSI cut-out setpoint, and resets by closing the circuit once pressure drops back to the 280 PSI cut-in setpoint — providing dependable, automatic high-side pressure protection.

Built to Supco’s exacting quality standards, the SHP400280 is a dependable replacement or upgrade choice for commercial refrigeration, HVAC compressor circuits, and other pressure-sensitive applications where consistent and accurate pressure control is critical.
