Protection device for protection measures against earth fault currents

摘要

A protection device for earth-leakage current protection circuit breakers or differential-current protection circuit breakers, in the case of which a protection conductor of the network to be protected is, in accordance with the specification, directed past the protection circuit breaker in a protection conductor branch. It is provided that a resistor, selected from an imaginary complex impedance, be connected in the protection conductor branch. IMAGE
