Jumo 60003433 Temperature limiter
The galvanized steel plate housing with ceramic base makes the 3-pole mechanical safety temperature limiter very robust and can also be used under harsh conditions. The used measuring system works according to the thermal expansion principle and can be used without any problem up to a maximum admissible sensor temperature of 414 °C. The smooth round sensor made of high-quality stainless steel has a diameter of 4 mm with a probe length of approx. 75 mm. The remote control line of the thermostat is also made of stainless steel and can be laid flexibly according to a bending radius of 5 mm. The maximum permissible ambient temperature at the switching head (protection class IP00) is 80 °C. The switch head mounting is done with the help of a mounting bridge by 2 screws M4 with a distance of 28mm. The switch-off temperature is fixed by the thermostat. The safety temperature limiter has a high switching point accuracy of +0/-30 K. A decisive advantage is that no additional power supply is required for measuring the temperature. The electrical connection is made at the flat plugs (A 6.3 x 0.8 DIN 46244) of the switching set, which can directly switch a maximum permissible switching power of AC 480 Volt / 30 A. After falling below the limit value around the danger temperature, the device can be unlocked simply by pressing a button. The safety temperature limiter has a wide range of applications and is suitable for all applications where 3 phases are to be switched simultaneously.This text is machine translated.
