603070 / 0070-7-671-000-00-2000-40-10-6-40-00-0 / 707, safety temperature limiter, 70 to 130 ° C, transmission 2000 mm, hat rail

Safety temperature limiter, 70 to 130 ° C, transmission 2000 mm, hat rail

Due to its innovative housing made of high-quality plastic, the 1-pole mechanical construction thermostat is suitable for mounting on a TH35 DIN EN 60715 hat rail or directly for wall mounting. 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 149 ° C. The smooth copper round sensor has a diameter of 6 mm with a sensor length of about 66 mm. The thermostatic transmission is also made of copper. With respect to a 5 mm bending radius, the transmission line can be moved after flexible. The maximum permissible ambient temperature on the housing (protection type IP20) is 55 ° C. With the help of a screwdriver, the desired shutdown temperature can be easily set on a scale. The set off temperature can be read at any time. The safety temperature limiter is characterized by a high switching point accuracy of + 0 / -5 K in the upper half of the scale. The built-in temperature compensation reduces ambient temperature influences at the head of the switch to a minimum. A key advantage is that no additional auxiliary energy is required for temperature measurement. The electrical connection is made by PushIn © terminals, which significantly reduces the installation time compared to conventional screw connections. The maximum permissible switching power is AC 230 Volt / 16 A. The switching contact (terminal 2) is opened after the set temperature is reached and the signal contact (terminal 4) is closed. The switching contact is automatically locked and can only be closed after cooling the temperature on the sensor by approx. 10 K will be unlocked manually again. When the temperature at the sensor is cooled below -20 ° C, the circuit between terminal 1 and terminal 2 also opens, but closes itself again when temperature increases. When the measuring system is destroyed, the circuit is opened permanently, and unlocking is no longer possible. The switching contact is then in a neutral position. The safety temperature limiter is very flexible and can be used for temperature monitoring in laboratory and climate conditions as well as in heating, climate, and ventilation technology. Other applications include the plastics industry, equipment and mechanical engineering, furnace construction and building automation. The device is approved in accordance with DIN EN 14597 and DGRL and has an EAC approval.
