Description
The Carrier HK02SB027 is an OEM replacement low pressure switch engineered to protect refrigerant circuits in Carrier heating and cooling systems. Designed to monitor suction-side refrigerant pressure, this switch opens the control circuit when pressure drops below the factory-set cut-out threshold, safeguarding the compressor and system components from damage caused by low refrigerant charge, restricted airflow, or other fault conditions.
Product Overview
This low pressure switch carries a 44-27# pressure rating, indicating a cut-out pressure of 44 PSIG and a cut-in (reset) pressure of 27 PSIG. It is a direct OEM replacement part for compatible Carrier equipment, ensuring proper fit, function, and reliability without the need for field calibration.
