Description
The Schneider Electric (Square D) 9013FSG52J33 DPST Pressure Switch is used to sense levels and switch wiring circuits within connected equipment. It operates through a diaphragm that reacts to water pressure changes, causing internal contacts to open or close within the preset 5070 PSI range, allowing an automatic response of motors or compressors. In boiler and water circulation HVAC systems, it operates as a monitoring and switching element within the control circuit. Mounted at the pressure connection point and wired into the system, it operates during consistent circuit operation.
