The electromechanical thermostat can be operated without additional auxiliary energy. It is available with various connection possibilities such as tab connectors, screw terminals, or push-in connections. Examples of application areas include electronic screw-in heaters or deep fryers and hobs in the catering sector.

The JUMO heatTHERM P300 is also available as a safety temperature limiter. In the event of a malfunction, the device will set the system being monitored to a safe operating status.

All JUMO thermostats from the heatTHERM series come with capillary break protection. In addition, they are characterized by high levels of process reliability and long-term stability. The maximum switching point deviation is only +/- 5 % calculated for a total operating life of 250,000 hours. The cadmium-free design makes the devices particularly environmentally friendly and RoHS compliant.
