It continuously monitors refrigerant discharge pressure and opens the safety circuit when pressure exceeds safe operating limits — protecting the compressor from catastrophic over-pressure damage. When it fails or trips erroneously, you'll see repeated high-pressure lockout fault codes, nuisance trips on hot days, or a system that won't run at all despite normal operating conditions.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at 395 PSI | Closes at 295 PSI | 240 VAC rated | 1\/8\" NPT thread | Sensata PS80 series | 6(6)A contact rating | PMAX 41 Bar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier factory part built to exact Sensata PS80 tolerances.
