Abstract

1. The use of an earth leakage circuit breaker having arranged in the secondary circuit of a sum current transformer (3), whose primary winding has a number of turns that is adequate at 50 Hz, a magnetic blocking device (4) as a frequency-independent earth leakage circuit breaker in a frequency band from about 16 2/3 Hz to 400 Hz.
