Abstract
Improvements in fault current protection switches, with an addition current transformer that has primary windings for coupling to a network ac circuit to be controlled, and a secondary winding to which the excitation winding of an electromagnet is connected of trigger acting on a maneuvering bolt for a maneuvering device, as well as with a capacitor connected between the secondary winding of the summation current transformer and the secondary winding of the firing electromagnet, forming the secondary winding, the excitation winding and the capacitor, a resonant circuit that is tuned to a frequency dependent on the service frequency in the current circuit to be controlled, characterized in that the resonant circuit is tuned to the frequency of the voltage that is induced in the secondary winding by a current of corrient defect e continuous, pulsating, flowing in the primary windings of the summation current transformer.
