Sirai P302 30A Presssurestat

Commercial pressurestat for 110~120/220~240V equipment, #P302-6. This is the part that regulates your boiler heating via a diaphragm that expands and contracts as the boiler steam pressure raises and lowers, activating the contacts and sending a signal to the heating element telling it to turn on or off. It is by far the most commonly used pressurestat. This is a purely mechanical part, and so there’s no micro-switch to go out. The diaphrams go bad, and the contacts get fried. But the it is essentially two or three pressurestats, depending on how many wires are used in your unit. There are six connections. When the contacts on the first set of contacts go bad, simply move the two wires over to the next available unused set.
