A circuit for monitoring currents (111 ... 161) in a plurality of branch circuits (Z11, ... Z 61) of a network (NEW), wherein at least one opto-coupler (H11, K11 ... H61, K61) is contained in each of the branch currents (Z11, ... Z 61) to be monitored per sender diode, the reception elements of the opto-coupler are serially mounted or mounted in parallel in at least one monitoring path (PF1, PF2) through which current flows, and the current in the at least one monitoring path is used by means of a detection circuit (HD, HS) for display and/or switching purposes. |
