Product Features

  • The PA404A is a pressure actuated high limit, safety control for steam heating boilers; it breaks an electrical circuit to shut down the burner if steam pressure rises above a safe level.
  • The PA404B is used with suspension-type unit heaters to make the fan circuit when a pressure rise indicates the presence of steam.
  • 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.
