Safety temperature limiter STB LS1 4035, 90/110°C

A safety temperature limiter (STB) is a component that interrupts the heating process of a heat generator when a previously set, maximum permissible temperature is reached (temperature limit value). This also applies if the connecting pipe breaks or there is a leak in the sensor system. A spring accumulator then closes a valve that interrupts the flow of the heat transfer medium. This protects the heat generator itself or a system connected to it from destruction. Accordingly, the STB only becomes effective if the temperature controller fails. The highest switching point of the temperature controller must be a certain distance from the switching point of the STB.
