602031 / 81-640-000-00-2000-40-10-6-20-13-460 / 707.7, safety temperature limiter, 50 to 300 ° C, transmission line 2000mm

Safety temperature limiter, 50 to 300 ° C, transmission line 2000mm

Due to its galvanized steel sheet housing, the 1-pole mechanical thermostat is very robust and can also be used under rough 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 345 ° C. The smooth round sensor made of stainless steel has a diameter of 6 mm with a sensor length of about 85 mm. The transmission of the thermostat is made of copper and can be moved flexibly with respect to a 5 mm bending radius. The first 460mm from the switch head are covered with an electrically insulating PVC protection hose. The device has a capillary fracture security, which opens the switching contact when the measuring system is destroyed and goes into a neutral position. The thermostatic unlocking is no longer possible. The maximum permissible ambient temperature at the switch head (protection type IP00) is 80 ° C. The temperature compensation reduces the ambient temperature effect on the head of the switch to a minimum. The switch head fastening is done by means of a mounting bridge by two screws M4 x 28. With the help of a screwdriver, the desired shutdown temperature can be easily set on a scale. The safety temperature limiter is characterized by a high switching point accuracy of + 0 / - 15 K in the upper scale. A key advantage is that no additional auxiliary energy is required for temperature measurement. The electrical connection is made to the flat plug (A 6.3 x 0.8 DIN 46244) of the switch set, which can directly switch a maximum permissible switching power of AC 230 Volt / 16 A. The thermostat has an unlocking difference of about 25 K in the upper scale (about 45 K at the beginning of the scale), after which the device can be unlocked simply by pressing a button. The safety temperature limiter is very flexible and can be used in the heating, air-conditioning, ventilation and the plastic industry, equipment and furnace construction, as well as for temperature monitoring in laboratory and air-conditioning. The device is approved in accordance with DIN EN 14597 and DGRL and has UL and EAC approval. The device is roHS-compliant and cadmium-free.
