JUMO 60002099 Sicherheitstemperaturbegrenzer,

Due to its shock-resistant case with high-quality plastic cover and aluminum die-cast lower part, the 1-pole mechanical surface-mounting thermostat is very robust and can also be used in rough conditions. The measuring system used operates on the fluid expansion principle and can be used without any problems up to a maximum permissible probe temperature of 575°C. The smooth round sensor made of stainless steel has a diameter of 6 mm with a probe length of approx. 127 mm. The capillary of the thermostat is also made of stainless steel and can be laid flexibly with a bending radius of 5 mm. he maximum permissible ambient temperature at the switch head (protection class IP54) is 80 °C and with the aid of a screwdriver, the desired switch-off temperature can be easily set on a scale after removing the case lid inside. If the temperature exceeds the set limit value at the probe, the circuit (terminal 2) is opened and automatically closes the additional signal contact (terminal 4). The microswitch is mechanically locked. After the danger temperature has fallen below approx. 15% of the scale range, the microswitch can be manually unlocked. The STB is characterized by a high switching point accuracy of +0/-5 % in upper third of scale. If the measuring system is damaged, the circuit is permanently opened and unlocking it is no longer possible. The switching contact is in a neutral position so that no contacts are switched. When the sensor cools down to a temperature below approx. -20 °C, the circuit is also opened, the STB can be manually unlocked by the restart button when the temperature rises above approx. -20 °C. A decisive advantage is that no additional auxiliary energy is necessary for temperature measurement. The electrical connection is made directly to the installed microswitch via screw terminals, which can directly switch a maximum permissible switching capacity of AC 230 V / 10 A. The safety temperature limiter can be used very flexibly and is used in heating, air conditioning and ventilation technology as well as in the plastics industry, in apparatus and mechanical engineering and in furnace construction, in district heating transfer stations and for temperature monitoring in laboratories and climatic chambers.The device is approved according to DIN EN 14597 and DGRL. It has also an EAC approval.
