3100U Series
Hermetically sealed. UL &/or CSA. Tight tolerances & differentials. Pre-set & tamper proof. SPST contacts. Mounting brackets, terminals.
Overview
The 3100U Series is a single-pole, single-throw switch activated by a snap-action bimetal disc. The case is laser welded to form a hermetically-sealed steel housing, with a glass-to-metal seal at the terminal junction. Temperature calibrations are pre-set at the factory. Each unit is thermally and mechanically inspected and tamperproof. They are available to open or close on temperature rise. A variety of mounting brackets and terminals is available. Used in high temperature control. 3100U 240 V: UL/CSA approved.
