Firstco E2125 High Pressure Cutout Switch 650 PSI

The Firstco E2125 is a high pressure cutout switch designed to protect HVAC systems from dangerous overpressure conditions. This essential safety component monitors refrigerant pressure levels and automatically shuts down the compressor when pressure exceeds safe operating limits.

Key Features:

• Cutout pressure rating: 650 PSI ±15 PSI
• Automatic reset functionality when pressure returns to safe levels
• Designed for use with residential and commercial HVAC condensing units
• Compatible with R-410A and other modern refrigerants
• Prevents compressor damage from excessive discharge pressure
• Wired in series with compressor control circuit

This high pressure switch serves as a critical safety device by opening the electrical circuit to the compressor when refrigerant pressure becomes dangerously high, preventing costly equipment damage and potential system failures. When pressure conditions return to normal operating range, the switch automatically resets to restore system operation. Also cross-referenced as TW02205, BLPS-YKH03, and 400-650R500R.
