Overtemperature protection circuit

摘要

The temperature protection circuit has two electrical connection terminals (39,40) connected with the electrical appliance (46) and one temperature-dependent switch (10). A controllable semiconductor valve (41) is provided for AC voltage (45) connected with the electrical apparatus. The controllable semiconductor valve is provided with two power connections (47,48) connected with one of the connection terminals and a control input (49) connected with the temperature-dependent switch over the switching unit (11).
