Panel-mounting thermostats monitor thermal processes. The thermostats are available as protection temperature monitors STW (STB) and protection temperature limiters STB. In fault condition, the STB sets the system being monitored to a safe operational state.
Panel-mounting thermostats operate on the principle of liquid expansion. The electrical switching device is a microswitch.
