Schneider Electric A9Z65440 Residual Current Circuit Breaker All-Current-Sensitive iID, 4P, 40A, Type B-SI, 300mA, selective

Acti 9 iID all-current-sensitive Residual Current Circuit Breaker. 4-pole, rated current 40A, Type B-SI Selective, rated residual current 300mA, operating voltage (Ue) 400 AC, 50Hz, insulation voltage 500V AC. Quick switch for low-wear switching of the contacts. With mechanical front-side fault indication (VisiTrip) to display trips due to residual current. Safe contact indication (VisiSafe) of the residual current circuit breaker, green indication ensures no voltage on the output side. Test button for regular functional testing. Dual connection terminals for two-sided connection of cables or busbars. Easy removal of the single unit when busbars are installed, thanks to the front-accessible fastening element. Additionally attachable auxiliary modules (optional) undervoltage trip (iMN), overvoltage trip (iMSU), shunt trip (iMX), auxiliary switch for status indication (iOF), fault signal switch (iSD). Type B-SI integrates SI technology, offering higher resistance against electrical disturbances. Protects against smooth DC residual currents in single or three-phase supply networks caused by variable frequency drives, inverters & emergency power supply. Color shade RAL 9003. Meets the following standards IEC/EN 61008-2-1,IEC/EN 62423,IEC 61543,VDE 0664.
