Jumo 60002262 Bang-bang Temperature limiter 575 °C (max.) 10 A relay

Its impact-resistant housing made from high quality plastic makes the 1-pin mechanical body thermostat very robust and can also be used under harsh conditions. The mounting of the housing takes place with two screws through the dfas housing base. The remote line outlet is lateral. The measuring system used works according to the principle of liquid expansion and can be used without any problem up to a maximum admissible sensor temperature of 575 °C. The remote control line of the thermostat is made of stainless steel and can be laid flexibly according to a bending radius of 5 mm. The device has a steel immersion tube with a conical diameter of 12 mm to 8 mm. The sleeve is attached by a 30 mm diameter sweatband. The sleeve is attached to the transmission line by means of a union nut with a thread G 3/4 inch and has an installation length of 200 mm. The maximum permissible ambient temperature on the housing (protection type IP54) is 80 °C. The desired shutdown temperature can be easily adjusted with the help of a screw driver after removing the cover on the inside on a scale. If the temperature at the temperature sensor exceeds the set limit, the circuit (clamp 2) is opened and the additional signal contact (clamp 4) is closed automatically. The micro switch is mechanically locked. After falling below the danger temperature by about 15% of the scale range, the micro switch can be unlocked manually. The safety temperature limiter has a high switching point accuracy of +0/-5% in the upper third of the scale. If the measuring system is destroyed, the circuit will be opened continuously and unlocking is then no longer possible. The switch contact is then in the neutral position so that no contacts are switched. If the sensor cools to a temperature below approx. -20 °C the circuit is also opened, only when the temperature rises above approx. -20 °C the STB can be unlocked manually by means of the restart button. A decisive advantage is that no additional power supply is required for measuring the temperature. The electrical connection is made by screw terminals directly on the micro switch built-in, which can directly switch a maximum permissible switching capacity of AC 230 Volt / 10 A. The safety temperature limiter is very flexible in use and is used in heating, air-conditioning and ventilation technology as well as in the plastics industry, apparatus and mechanical engineering as well as in furnace construction, in district heating transfer stations and for temperature monitoring in laboratories and climate chambers. The device is approved according to DIN EN 14597 and DGRL and has an EAC approval.
