Residual current circuit breaker Acti 9 iID, 1.5kA (IEC/EN 61008-1). 2-pole, nominal current 40A, earth fault sensitivity 300mA, earth fault protection class type A, selective, operating voltage (Ue) 230V AC, insulation voltage (Ui) 500V AC. Guarantees additional protection in the event of direct contact (= 30mA). Fault protection in the event of indirect contact, e.g. in the event of insulation faults (= 100mA, = 300mA). Fault protection in construction power distribution boards (500mA). Switching and disconnecting circuits. Snap action for low-wear switching of the contacts. With mechanical front-side fault indication display (VisiTrip) to indicate tripping due to overload or short circuit. Safe contact display (VisiSafe) of the residual current circuit breaker, with a green display to ensure that there is no voltage on the output side. Test button for regular function testing. Double connection terminals for connecting cables or phase rails on both sides. Easy removal of the individual device with the phase rail installed, thanks to the fastening element accessible from the front. Selective version - to ensure correct differentiation between the different residual current circuit breakers and the tripping of the device closest to the defect. Additional auxiliary modules that can be added in series (optional) - undervoltage release (iMN), overvoltage release (iMSU), shunt release (iMX), auxiliary switch for status reporting (iOF), fault reporting switch (iSD). Tool-free installation on the left side of the device. Color RAL 9003. The residual current circuit breaker iID meets the following standards - IEC/EN 61008-1 and IEC/EN 60947-2. This series is also VDE certified!
