Product Data
| 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.
