The 3NT thermostat from Sensata Technologies is a new, custom-built automatic reset thermostat designed to meet your specific application requirements. Its patented, tamper–proof Klixon snap–acting bimetal disc provides reliable, repeatable switch actuation for electrical loads ranging from dry circuits to 10A @ 240Vac.

The unique, dry seal 3NT design protects the switch from environmental hazards such as water, dust, oil, etc. without the use of epoxies or additives, reducing cycle times and environmental concerns.

A choice of o-ring materials is available to assure a lasting seal between a metal cup and protective PBT housing over a wide range of temperatures and chemical exposures. The silicon rubber grommets which seal around each wire lead have been proven by years of automotive use.

The dry seal also allows direct integration of the thermostat into a wire harness, eliminating extra connectors.
