Product Details

Description

Ensure the safety and efficiency of your HVAC or refrigeration system with this High Pressure Switch with Wire Leads. This essential air-proving component is designed to protect compressors and system components by monitoring internal pressure levels. When the system reaches 650 PSIG, the switch interrupts the electrical circuit to prevent equipment damage, automatically resetting once pressure drops to 450 PSIG. Built for durability and precise response, this high-pressure cutout is vital for air conditioning units and heat pump systems. The included wire leads facilitate a secure and straightforward connection during repair or maintenance, making it a reliable choice for maintaining optimal cooling performance.
