Square D by Schneider Electric 9013FSG2J24M4 Air-Pump Pressure Switch - NEMA 1 Rated, 40-60 psi Adjustable Range, 2-Pack Electromechanical Diaphragm Switch - Automatic Control for Water Pumps, Air Compressors & HVAC Systems

This Square D Pumptrol 9013FSG2J24M4 electromechanical pressure switch with 40-60 psi pressure setting range activates an electrically driven water pump within a power circuit when the adjustable rising and falling thresholds are reached. The NEMA 1 enclosure has a 1/4" NPSF internal fluid connection and screw clamp terminals. The switch works with a 1. 5 hp or less pump. The adjustable differential range is 15-30 psi and the cut-out range is 20-65 psi. The low-pressure cut-off (auto-start-off) operates at approximately 10 psig below the cut-in and will turn off the pump. The enclosure is National Electrical Manufacturers Association (NEMA) Type 1 and Ingress Protection (IP) 20 rated. The switch is Underwriters Laboratory (UL) Listed and Canadian Standards Association (CSA) Certified. Square D Pumptrol pressure switches are manufactured by Schneider Electric.
