Temperature monitoring device has its own 30 In the case of an electric motor, an encapsulated switch is actuated so that at least two switches are used.Cooling machine, it is recommended, if they are necessary, to switch the motor on from the mains with one pole 1151 870). It's winding thermostat is. This winding thermostat also known, the main phase with a normal can be secured due to the aforementioned advantages very small thermal circuit breaker, the auxiliary phase 35 and at any point, z. B. in the winding head, with a fuse on the other hand, which are in contact with the main winding,

The melting point is shown schematically, the circuit diagram of an inventive fuse must be replaced after each response, if the electric motor is illustrated.
the. It is then also known to provide a single switch with an auxiliary winding 2 supply line, which is provided with a main winding 3 in the common An electric motor 1. The current via a linkage, optionally from the monitoring system, is fed to both branches via a common main device of the main winding or the over-switch 4. A PTC resistor 5 is activated in the auxiliary winding branch. In the municipalities can (German Patent 827 377). This single supply line is the contacts of a protective switch, but if it has a single-pole full switch for the motor, which is controlled by a temperature sensor 7 on which is to be constantly disconnected from the mains, the main winding must be so large,
that it is able to switch the entire short-circuit current of the circuit breaker 6, 7 is preferably in the form of a motor. 50 of a winding built into the main winding
