Carrier KAALP0401PUR Pressure Switch

The Carrier KAALP0401PUR is a technical-grade Low Pressure Switch Kit specifically engineered for HVACR systems utilizing Puron (R-410A) refrigerant. As a critical safety control, this switch monitors suction line pressure to protect the compressor from catastrophic failure caused by refrigerant loss, restricted airflow, or a frozen evaporator coil. Designed for a wide range of Carrier, Bryant, and Payne equipment, it features a factory-calibrated cut-out at 50 PSI and a cut-in at 95 PSI, ensuring precise cycling during low-pressure events. This OEM kit includes the pressure switch, an adapter tee, flare gaskets, and an adapter tube, providing a complete field-replacement solution for residential and commercial units, including the 24AB and 113ANA series. By maintaining system charge monitoring and preventing operation in vacuum conditions, the KAALP0401PUR preserves the integrity of the refrigeration circuit in harsh environments and standard split-system applications.

• OEM Compatibility: Precision-engineered for Carrier Puron systems, ensuring exact electrical and mechanical fit for seamless field integration.
• Enhanced System Protection: Prevents compressor overheating and oil slugging by deactivating the system when refrigerant levels drop below 50 PSI.
• Comprehensive Kit: Includes flare gaskets and an adapter tee to minimize leak points and reduce total installation time on the job site.
• R-410A Optimized: Specifically calibrated for high-pressure Puron refrigerant, resisting the corrosive effects of POE oils and maintaining setpoint accuracy.

• What are the specific pressure settings for this switch? The KAALP0401PUR is designed to cut-out at 50 PSI (±5) and resets (cut-in) at 95 PSI (±10).
• Is this switch compatible with R-22 systems? No, this low pressure switch is calibrated specifically for Puron (R-410A) systems; using it with R-22 will result in improper system cycling and potential hardware damage.
• When should I replace the low pressure switch? Replace the senses if you observe the system failing to trip during a known low-charge state or if there is visible oil leakage at the switch bellows or electrical terminals.
