Description
The Marvair 70080 High Pressure Switch monitors refrigerant pressure levels in compatible cooling and air conditioning equipment. Commonly applied in condensing units and refrigeration systems, it responds to pressure changes to help regulate equipment operation and protect system components. The switch opens when pressure reaches 400 PSI, interrupting the control circuit, and returns to its normal state when pressure decreases to 300 PSI. Installed as part of HVAC systems, it works with control and safety circuits to monitor operating conditions and support coordinated equipment operation in commercial and residential cooling applications.
