Schneider Electric Circuit Breaker 18638: additional details
Acti 9 NG125N circuit breaker, 25kA (IEC/EN 60947-2). 2-pole, rated current 50A, C characteristic, operating voltage (Ue) 380-415V AC, insulation voltage (Ui) 690V AC. Protects the circuit against short-circuit currents. Protects the circuit against overload currents. The tripping is indicated by the central position of the switch lever and by a red mechanical display on the front of the device. Test button to check the tripping mechanism. Top or bottom feed. Jump switching for low-wear contact switching. Tripping unit technology: thermomagnetic. Additional attachable auxiliary modules (optional): display of switching position, fault tripping, operational 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: 3303430186380.
