* Changes in temperature are conducted through the metallic housing and directly onto a bimetal disc which snaps over to operate a set of contacts after a pre-determined temperature has been reached. The protector automatically resets when safe operating temperatures are restored.
* Particularly suitable for clamping onto suction and discharge lines on refrigeration and air-conditioning compressors, or heat-exchange hot-water systems. They can provide defrost termination or overheat safety control, with protection from weather, moisture or dust.
* SPST single-pole single-throw, which make or break contacts only. The operation of the contacts are factory set so that they either make (normally open) or break (normally closed) an electric circuit on temperature rise, and automatically reset.
* SPDT single-pole double-throw, with a change-over contact option. The common line is interrupted from one circuit and connected to another circuit simultaneously on temperature rise.
