Abstract

The circuit provides a supply current derived from a network of several conductors for leakage current cut-out switches. In order to maintain the auxiliary voltage (U2) in the case of failure of the neutral wire (N), three rectifiers (D4, D5, D6) are used. These are connected to the neutral line and to the live lines (L1-3) via resistors (R1-3). The points (a.b.c.) connecting rectifiers (D4-6) and their respective resistances are each connected through further rectifiers (D1-3) to a single line. This line (e) forms a supplementary neutral point.
