Signal for overcurrent releases tripped4) Electrical signalling of electronicreleases trippedThe following signals are available after the electronic trip unithas tripped:4a) Electrical signalling of electronic trip units trippedThis allows remote signalling (electrical using switch) that thecircuit-breaker is open following operation of the overcurrentreleases. The mechanical signalling pushbutton must berearmed to reset the circuit-breaker.Reference figure in electrical circuit diagrams: S51 (13)51SDC200144F00011SDC200141F00014b) Electrical signalling of electronic releases tripped withremote reset commandThis allows remote signalling (electrical using switch) that thecircuit-breaker is open following operation of the overcurrentreleases. With this accessory, it is possible to reset the mechanicalsignalling pushbutton via an electrical coil from aremote command, which also allows the circuit-breaker to bereset.Available reset coils24-30 V AC/DC220-240 V AC/DC110-130 V AC/DCReference figure in electrical circuit diagrams: S51 (14)ABB SACE 5/11
