FSG 20/40 Pressure Switch

The Square D FSG220 is designed with a Pumptrol pressure switch that is used to control the pressure of electrically-driven water pumps for jet, submersible and reciprocating system applications. Turns on at 20 PSI and off at 40 PSI. This sensor handles fresh and sea water that does not exceed 158 degrees Fahrenheit. It is made with 2 NC Snap Action contacts. The components which have contact with fluid are made of Nitrile, Zinc plated steel, and Nylon 6/6.
