604100 / 20-5-140-3000-0-40 / 404, frost protection thermostat, -10 to 15 ° C, sensor line 3000 mm, IP65

Frost protection thermostat, -10 to 15 ° C, sensor line 3000 mm, IP65

Due to its high-quality plastic case, the 1-pole mechanical construction thermostat is very robust with switching contact and can also be used under harsh conditions. The measuring system used can be used without any problems up to a maximum permissible sensor temperature of 120 ° C. The thermostatic sensor is made of copper. With respect to a 20 mm bending radius, the line can be moved flexibly as required. The maximum permissible ambient temperature on the housing is 80 ° C. For physical reasons, the ambient temperature on the housing must be 2 K above the set switching point. The housing is mounted directly on the housing body as a wall assembly. With the help of a screwdriver, the desired shutdown temperature can be easily adjusted on a scale after the case cover has been removed. The set shut-off temperature can be seen at any time by means of a vision window in the housing cover. The safety temperature guard is characterized by a high switching point accuracy of + / -2 K. 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. If the temperature at the sensor line is less than the set value at a length of 15 cm, the circuit terminal 1 - 2 is opened and the circuit terminal 1 - 4 is automatically closed. The thermostat has a switching difference (hysteresis) of about 0.5 to 2.5 K and automatically switches back to the state of origin after the switch-off temperature is exceeded. When the temperature at the sensor is cooled below -20 ° C, the circuit opens between terminal 1 and terminal 2 and, however, closes itself again when temperature increases. When the measuring system is destroyed, the circuit is opened permanently, the switching contact is then in a neutral position. The safety temperature guard is very flexible and can be used in building automation as well as in heating, air conditioning, and ventilation. The device has an EAC approval.
