Brief description

Thermostats control and monitor thermal processes. Thermostats in the ATH series can be supplied as temperature controllers TR, temperature monitors TW, temperature limiters TB, safety temperature monitors STW (STB) and safety temperature limiters STB. In fault condition, the STB sets the system being monitored to a safe operational state.

Surface-mounting thermostats operate on the principle of liquid expansion, with a microswitch serving as the electrical switching device.
