OEM Carrier High Pressure Switch HK02ZA395 — 395/295 PSI for Model PY2PEB060130AB

This OEM high pressure switch is the factory-specified refrigerant-side safety control for the Carrier PY2PEB060130AB packaged unit. Mounted on the high-pressure side of the refrigerant circuit, it monitors system pressure and opens the control circuit to shut down the compressor if pressure exceeds the factory-set limit, protecting against catastrophic compressor failure, refrigerant line rupture, and heat exchanger damage. Common failure symptoms include nuisance compressor lockout, system short-cycling on high pressure fault codes, or a compressor that won't start even when refrigerant charge is confirmed correct.

• Specs: Opens at 395 PSI | Closes at 295 PSI | 1/8" NPT fine thread port | 6(6)A @ 240 VAC | Sensata PS80-03-0018 platform | PMAX 41B rated
• OEM vs Generic: The OEM Carrier HK02ZA395 is manufactured by Sensata to exact factory cut-out tolerances (±2 PSI). Generic substitutes often carry wider tolerances that can allow unsafe pressure excursions or cause premature nuisance trips, shortening compressor life.
• Install difficulty: 3/5 — Refrigerant-side work requires an EPA 608 certified technician. System must be recovered or isolated before replacing the switch. Tools needed: manifold gauge set, 1/8" NPT tap or flare fitting wrench, refrigerant-rated thread sealant, multimeter. Confirm system pressures are normal after reinstall before restart.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
