    3150 Series

    Hermetically sealed. UL &/or CSA. Pre-set & tamper proof. Low profile

    Overview

    The 3150 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. The low silhouette and compact design often make it especially well suited for applications that require miniaturization.
