Schneider Electric Circuit Breaker 18731: Additional Details
Acti 9 NG125H Circuit Breaker, 36kA (IEC/EN 60947-2). 2-pole, rated current 63A, C characteristic, operating voltage (Ue) 380-415V AC, insulation voltage (Ui) 690V AC. Protects the circuit against short-circuit currents and overload currents. The tripping is indicated by the middle position of the switch lever and a red mechanical indicator on the front of the device. Test button to check the tripping mechanism. Feed-in from the top or bottom. Jump switching for low-wear contact switching. Tripping Unit Technology: thermomagnetic. Additional snap-on auxiliary modules (optional): indication of switching position, fault tripping, working current tripping, undervoltage tripping, overvoltage tripping. The NG125H circuit breaker complies with the following standards: IEC/EN 60947-2. Furthermore, this series is VDE certified.
