The PA404 is a series 40 (2-wire, SPST) pressuretrol controller for use in 24, 120, 240 or 277 V control circuits or in self powered (millivoltage) applications.

  • It breaks an electrical circuit to shut down the burner if steam pressure rises above a safe level
  • Each model contains an SPST micro switch snap-acting switch
  • Sensitive pressure-actuated diaphragm expands or contracts with pressure variations, moving a lever mechanism which operates the snap switch
  • A screw on top of the case allows set point adjustment without removing the cover
  • Differential is adjusted by means of a dial located inside the case
