Square D FSG2J20 pressure switch with dry-running protection

The FSG 2J20 pressure switch with dry-running protection is designed to automate the operation of an electric pump, turning it on when the pressure in the water supply system drops below a set limit (taps are opened), and turning the electric pump off when the upper set limit is reached (taps are closed).

The FSG2J20 pressure switch is recommended for use in situations where the pump may run dry during operation, as the FSG 2J20 pressure switch is equipped with a dry-run protection feature. (When the system pressure reaches 0.4 bar or less, the switch shuts off the pump.)

Technical characteristics of the FSG2J20 pressure switch

• Power voltage: 220 V, 50/60 Hz
• Current up to: 16 A
• Pressure range: 1 – 5 bar
• Dry run shut-off: 0.5 bar
• Rp=1/4"
