Abstract

The patent is concerned with the connections between the circuit breaker and the multiple switch. The structure consists of the leakage-current circuit breaker (1), the automatic multipole switch (2), and transverse electric lines (3a, 3b) which lead from its load current transformer to some automatic switch connections and to external connections soldered to terminals (4). A cover (7) is placed over the transverse lines, and is fixed in position by flexible bent clamps (5) which ifjts into the socket of the holes (7a) in the cover, and which are fixed thus by a screw in the hole and a nut attached to terminal (4a).
