Beschreibung
Zusammenfassung:	A device for providing automatic connect/disconnect function for a starting capacitor used in conjunction with an async electric motor, comprises two capacitors, the first being used for the starting of the motor and the second for normal running of the motor. A connecting and disconnecting device for the starting capacitor is connected directly to the feeding phase of the capacitors and is fed with the same voltage which feeds the running capacitor. The disconnecting device consists of at least of a timing circuit which acts on a relay to disconnect the starting capacitor after a given time immediately after the motor has started.
