Jumo Surface-mounted thermostat as TR Switching capacityAC 230V/10A Control range+20+150°C

The single-pole mechanical surface-mounted thermostat is very robust due to its impact-resistant housing with a high-quality plastic cover and aluminum die-cast base, making it suitable for use in harsh conditions. The measuring system operates on the principle of liquid expansion and can be used without issues up to a maximum allowable sensor temperature of 175 °C. The smooth round sensor made of copper has a diameter of 6 mm and a sensor length of approximately 88 mm. The thermostat's remote cable is also made of copper and can be flexibly installed with a bending radius of 5 mm. The maximum allowable ambient temperature at the housing (protection class IP54) is 80 °C. Using a setpoint adjuster, the desired switch-off temperature can be easily set on a scale. The temperature controller features a high switching point accuracy of +/-1.5% in the upper third of the scale. A significant advantage is that no additional auxiliary power is required for temperature measurement. The electrical connection is made via screw terminals directly at the installed microswitch, which can switch a maximum allowable switching power of AC 230 volts / 10 A directly. The thermostat has a switching differential (hysteresis) of about 3 to 4% of the scale range and automatically returns to the original state after falling below the switch-off temperature by this value. The temperature controller is highly versatile and is used in heating, air conditioning, and ventilation technology, as well as in the plastics industry, apparatus and mechanical engineering, oven construction, and for temperature monitoring in laboratories and climate chambers. The device is approved according to DIN EN 14597 and has an EAC certification.
