Jumo Capillary Thermostat, Automatic Reset, Surface Mount

The Jumo 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 230°C.The protection tube made of high quality stainless steel (material no. 1.4571) has a diameter of 8 mm and is fixed with a thread G 1/2 form A according to DIN 3852/2. 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.
