603021 / 70-1-066-0-00-20-13-46-150-8-6 / 000, safety temperature limiter, 60 to 130 ° C, installation length 150 mm

Safety temperature limiter, 60 to 130 ° C, installation length 150 mm

Due to its impact-resistant housing with high-quality plastic cover and aluminium-cast base, the 1-pole mechanical construction thermostat is very robust and can also be used under harsh conditions. The measuring system used is based on the fluid expansion principle and can be used without any problems up to a maximum permissible sensor temperature of 150 ° C. The diving tube made of brass nickel has a diameter of 8 mm. The mounting is done by a thread G1 / 2 form A according to DIN 3852 / 2. The maximum permissible ambient temperature on the housing (protection type IP54) is 80 ° C. With the help of a screwdriver, the desired switch-off temperature can be easily set on a scale after the case cover is removed. If the temperature at the temperature sensor exceeds the set limit, the circuit is opened and the microswitch is mechanically locked. After the temperature of the danger is below about 10% of the scale can be unlocked manually. The safety temperature limiter is characterized by a high switching point accuracy of + 0 / -5% in the upper scale. When the measuring system is destroyed, the circuit is opened permanently, and unlocking is no longer possible. When the sensor is cooled to a temperature below approx. -20 ° C the circuit is also opened, only when the temperature is increased by about -20 ° C can be unlocked by hand. A key advantage is that no additional auxiliary energy is required for temperature measurement. The electrical connection is made by screw terminals directly on the built-in microswitch, which can directly switch a maximum permissible switching power of AC 230 Volt / 10 A. The safety temperature limiter is very flexible and can be used in both heating, air conditioning, ventilation and the plastics industry, equipment and mechanical engineering as well as in furnace construction, district heating and temperature monitoring in laboratory and climate conditions. The device is approved in accordance with DIN EN 14597 and DGRL and has an EAC approval.
