Description
The Schneider Electric (Square D) 9013GHG2J57 Pressure Switch controls equipment operation by activating or deactivating circuits based on pressure changes in HVAC systems. It operates within a 40 to 200 PSI range, with a cut-in setting of 120 PSI and cut-out at 150 PSI, using a double-pole double-throw contact arrangement for flexible control. This switch is used in compressors or pressure-regulated equipment, where it responds to system pressure conditions. Its role is to maintain controlled operation by managing pressure-dependent switching and protecting connected components.
