Schneider Electric 9013FHG42J55 Pressure Switch

The Schneider Electric 9013FHG42J55 Pumptrol pressure switch is a fixed-differential, single-port compressor switch that automatically controls a pump or air compressor by opening and closing its contacts as pressure changes. It operates within a 110–150 psi window, with the off setting fixed at 150 psi (J55 code), and is part of the 9013FHG family used in low-horsepower, fixed-differential pumping applications. This model is a single-port variant within the 9013FHG family, commonly used as a replacement in Square D Pumptrol installations for low-horsepower duty. The 9013FHG family lists a maximum burst pressure of 220 psig, aligning with the rugged performance expected in compressor and pump service.
