Description
The Schneider Electric (Square D) 9013FHG49J59X Pressure Switch operates as a DPST switch which controls HVAC system pressure in specific ranges. The part operates between 60 to 200 PSI while using 135 PSI as its “ON” set point and 175 PSI as its “OFF” set point to achieve efficient operation. The part protects equipment from high pressure damage by monitoring pressure levels in air compressors and refrigeration units. The exact control capabilities of this part enhance system performance while decreasing energy usage and extending of HVAC components.
