Residual current circuit breaker Acti 9 iID, 1.5 kA (IEC/EN 61008-1). 4-pole, rated current 40 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 circuits. Snap-action mechanism for low-wear switching of contacts. Equipped with a mechanical front-facing fault indication (VisiTrip) to display tripping due to overload or short circuit. Safe contact indication (VisiSafe) of the residual current circuit breaker, with a green display indicating safety from voltage 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 with installed busbar, 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.
