Jumo Capillary Thermostat, 120°C Max, NC, Automatic Reset, Surface Mount

The Jumo Mechanical Surface Mounting Double Thermostat is very robust and can also be used in rough conditions. The electrical connection is made by screw terminals connected directly to the installed microswitches, which can directly switch a maximum permissible switching capacity of AC 230 V / 10 A. The measuring systems used operate according to the fluid expansion principle and can be used up to a maximum permissible probe temperature of 140°C without any problems. It is fastened by a thread G 1/2 Form A according to DIN 3852/2. The maximum permissible ambient temperature at the case (protection class IP54) is 80 °C. The thermostat can be used very flexibly 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 climatic chambers.
