Residual current circuit breaker Acti 9 iID, 1.5 kA (IEC/EN 61008-1). 4-pole, rated current 100 A, earth fault sensitivity 100 mA, earth fault protection class type A, operating voltage (Ue) 400 V AC, insulation voltage (Ui) 500 V AC. Provides additional protection against direct contact (30 mA). Fault protection against indirect contact, e.g., in case of insulation faults (100 mA, 300 mA). Fault protection in construction site distribution boards (500 mA). Switching and disconnecting of circuits. Jump switching for low-wear contact operation. With mechanical front-facing fault indication (VisiTrip) to show tripping due to overload or short circuit. Safe contact indication (VisiSafe) of the residual current circuit breaker, with green indication ensuring voltage-free status on the outgoing side. Test button for regular functional testing. Double connection terminals for dual-side connection of cables or phase bars. Easy removal of the individual device when the phase bar is installed, thanks to the front-accessible fastening element. Additional snap-on auxiliary modules (optional) - undervoltage release (iMN), overvoltage release (iMSU), working current release (iMX), auxiliary switch for status indication (iOF), fault indication switch (iSD). Tool-free mounting on the left side of the device. Color shade RAL 9003. The residual current circuit breaker iID complies with the following standards: IEC/EN 61008-1 and IEC/EN 60947-2. Additionally, this series is VDE certified.
