Residual current circuit breaker Acti 9 iID, 1.5kA (IEC/EN 61008-1). 4-pole, rated current 100A, earth fault sensitivity 30mA, earth fault protection class type A, operating voltage (Ue) 400V AC, insulation voltage (Ui) 500V AC. Provides additional protection against direct contact (≤ 30mA). Fault protection against indirect contact, e.g., in case of insulation faults (≥ 100mA, ≤ 300mA). Fault protection in construction site distribution boards (500mA). Switching and isolating circuits. Jump switching for low-wear contact operation. Equipped with a mechanical front-side fault indication (VisiTrip) to show tripping due to overload or short circuit. Safe contact indication (VisiSafe) of the residual current circuit breaker, with a green indication ensuring voltage-free safety on the outgoing side. Test button for regular functional testing. Double connection terminals for dual-sided connection of cables or busbars. Easy removal of the individual device when a busbar 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. Furthermore, this series is VDE certified.
