Square D Loss of Prime Pressure Switch 207kPa(30PSI)cut-in 345kPA(50PSI)cut-out

Loss of Prime Pressure Switch

Standard pressure setting: 30 PSI cut-in , 50 PSI cut-out

Maximum pressure setting: 60 PSI cut-in, 80 PSI cut-out

Bottom connection: ¼" FNPT (Female pipe thread)

Main spring adjustment (large spring): Turn clockwise to increase cut-in and cut-out pressure (maintaining 20 PSI differential) Turn counter-clockwise to decrease.

Differential adjustment (small spring): Turn clockwise to increase cut-out pressure without affecting cut-in. Turn counter-clockwise to decrease. Capacity: 2 HP @ 115 Volts, 3 HP @ 230 volts single phase, 5 HP @ 230 volts three phase

Note: We recommend that you maintain a 20-PSI differential
