Surface-mounted single thermostats ATH

Description

Brief description
The devices of the ATH series are available as temperature controllers (TR), temperature limiters (TB), temperature monitors (TW), safety temperature monitors (STW), and safety temperature limiters (STB). In the event of a malfunction the STB sets the system being monitored to a safe operating status.
Surface-mounted thermostats operate according to the fluid expansion principle. A microswitch is used as an electrical switching element.
