Carrier HK02SB024 Low Pressure Switch 117/54 PSI

The Carrier HK02SB024 is a genuine OEM low pressure switch designed to monitor and protect HVAC systems from low refrigerant pressure conditions. This precision safety control automatically activates at 117 PSI and deactivates at 54 PSI, ensuring optimal system performance while protecting the compressor from damage.

Key Features:

• Cut-in pressure: 117 PSI
• Cut-out pressure: 54 PSI
• Automatic reset functionality for convenient operation
• Genuine Carrier OEM part for guaranteed compatibility
• Rated at 6A, 240VAC for reliable switching capacity
• Designed for refrigeration and air conditioning applications

This low pressure switch continuously monitors refrigerant pressure in the system. When pressure drops below the safe threshold of 54 PSI, the switch opens the electrical circuit to shut down the compressor, preventing catastrophic damage from low-pressure conditions. Once system pressure recovers to 117 PSI, the switch automatically resets and allows normal operation to resume. Essential for maintaining system efficiency and extending equipment life in Carrier, Bryant, and Payne HVAC units.
