Carrier 312926-258 Pressure Switch
The Carrier 312926-258 Low Pressure Switch is a factory-authorized OEM replacement part designed for high-precision refrigerant monitoring in residential air conditioners and heat pump systems. This heavy-duty SPST pressure control is calibrated to open at 23 PSI and close at 55 PSI, providing a critical safety cut-out to prevent compressor operation during low-charge conditions or evaporator freeze-ups. Built with a robust metal casing and a high-performance Sensata or Wilspec internal sensing element, it ensures long-term reliability in demanding HVACR refrigeration cycles. The unit features a 2-inch sensor body with 48-inch factory-stripped leads for straightforward terminal integration, maintaining a maximum operating pressure of 696 PSI. For service technicians, utilizing this Carrier 55-23 PSI switch preserves the original equipment's engineering specifications and system balance, eliminating the calibration drift often seen with generic aftermarket controls. Its compact 0.75-inch width allows for installation in tight cabinet clearances common in modern high-efficiency condensing units.
Key Benefits- System Protection: Actively monitors suction line pressure to prevent compressor damage from sub-ambient conditions or loss of charge.
- OEM Calibration: Factory-set 23 PSI open and 55 PSI close points ensure the Carrier 312926-258 meets exact manufacturer performance curves.
- Durable Construction: Engineered with copper contacts and a corrosion-resistant brass inlet for stable electrical continuity across 240V circuits.
- Versatile Compatibility: Fits a wide range of Carrier, Bryant, and Payne units, including 213A, 215B, and 25HB series models.
Is the Carrier 312926-258 compatible with R-410A systems?
Yes, this switch is rated for a maximum pressure of 696 PSI, making it suitable for the higher operating pressures of R-410A residential split systems and heat pumps.
Does this switch require manual resetting?
No, this is an automatic reset switch. It will automatically close the circuit once the system pressure rises back to the 55 PSI set point.
What is the lead length for electrical termination?
The switch comes equipped with 48-inch color-coded leads, providing ample length for routing through the control box and connecting to the defrost board or contactor coil.
