Description
The 3100 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 manufactured and
tested to meet or exceed critical commercial and industrial specifications.
