Abstract

The device has at least one input and one output terminal per pole path connected together via a connecting line with at least one current measurement device. At least one connecting line contains a switch with rails (1,2) for carrying away a spark between fixed (8) and movable (9) contacts. At least one adjacent line (10) is arranged so that its magnetic field (4',5') augments that (4) in the line with the switch when a spark (3) is present.
