Electrical

  • Up to 2 HP at 230 V single-phase; verify against the label
  • DPST snap action
  • Not for three-phase motor current — use pilot duty plus a contactor

Size against motor full-load amps with the motor amperage calculator, and check feeder sizing with the voltage drop calculator.

Adjustment

  1. Single range nut. The differential is fixed; do not force the smaller nut on a fixed-differential body.
  2. Confirm the tank ASME plate allows 175 psi before setting cut-out there.
Before you open the cover

Kill power at the disconnect and lock out. Bleed the tank to 0 psi. Never set cut-out above the tank data-plate MAWP. Verify your numbers first in the cut-in / cut-out calculator.

Best fit

  • Two-stage 175 psi shop compressors
  • Replacing obsolete four-port OEM switches

Watch out

  • The safety valve must be rated at or below the tank rating — replace it if you raise cut-out.
  • Four-port bodies invite extra tees; every unused port is a future leak. Plug them properly.
