Schneider Electric Circuit Breaker 18663: further details
Acti 9 NG125N Circuit Breaker, 25 kA (IEC/EN 60947-2). 4-pole, rated current 10 A, C-characteristic, operating voltage (Ue) 380-415 V AC, insulation voltage (Ui) 690 V AC. Protects the circuit against short-circuit currents and overload currents. The tripping is indicated by the middle position of the switching lever and a red mechanical display on the front of the device. Test button to check the tripping mechanism. Feed from above or below. Jump switching for low-wear contact switching. Tripping Unit Technology: thermomagnetic. Additional snap-on auxiliary modules (optional): switching position display, fault tripping, working current tripping, undervoltage tripping, overvoltage tripping. The NG125N circuit breaker complies with the following standards: IEC/EN 60947-2. Furthermore, this series is VDE certified. EAN: 3303430186632.
