The Carrier HK02SB031 Low Pressure Switch is a safety control part used to monitor refrigerant pressure levels in air conditioning and refrigeration units in HVAC systems. It works by sensing suction pressure within the refrigerant line and automatically opening or closing electrical contacts when pressure drops below the preset limit helping protect the compressor from damage caused by low refrigerant charge or restricted airflow. It is used in cooling and heat pump equipment and it improves system safety, supports reliable compressor operation, and helps maintain efficient performance. It enhances equipment protection, reduces downtime risks and ensures dependable operation in systems.
