The 3MS1 QPL Series consists of a single pole, single throw switch activated by a snap-action bimetal disc. Temperature calibrations are pre-set at the factory, and each unit is 100% thermally and mechanically inspected. It is available to open or close on temperature rise. The case is laser welded to form a hermetically sealed steel housing with a glass-to-metal seal at the terminal junction. It is qualified to MIL-S-24236 and is QPL listed for military applications.
