Abstract
The invention relates to a circuit breaker for cutting off the two AC supply leads of an electrical receiver from the time of creation of a leakage current F between said receiver and ground through a human body. This circuit breaker comprises a differential transformer generating a faulty voltage V.sub.O, a relay with contacts open when it is not energized, and means (A.sub.1,A.sub.2, . . . A.sub.n ; R.sub.1,R.sub.2 . . . R.sub.n) supplied by the system, adapted to exploit the voltage V.sub.O for the purposes of energizing the relay if the current F is dangerous or at least unpleasant in its intensity and/or its duration, without however being sensitive to disturbances.
