Only specifically listed as a part for the La Spaziale S2 model.

The Sirai (pronounced "SUH-RYE") commercial pressurestat for 110~120/220~240V equipment, #P203T01. 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. This is the less-common two-pole version, model P203T01. One of the major differences is the lower amperage. This switch can only function with 20 amps or less! Additionally, the wiring on this version is connected through the top portion of the switch. There's a snap-on lid with two press-in tabs on the upper sides of the cover. Found in La Spaziale and Rocket espresso machines.
