Schneider Electric 18821 Circuit breaker NG125L, 4P, 10A, C characteristic

The Acti 9 NG125L circuit breaker, 50kA (IEC/EN 60947-2), is a 4-pole device with a nominal current of 10A and a C-type tripping characteristic. It is designed for operating voltages (Ue) of 380-415V AC and has an insulation voltage (Ui) of 690V AC. This breaker provides protection for electrical circuits against short-circuit currents as well as overload currents. Tripping is indicated by the switch lever's middle position and a red mechanical signal on the front of the device. A test button allows for the verification of the tripping mechanism. The device permits either top or bottom line feed and features a switching mechanism that reduces contact wear. It uses thermomagnetic technology for the tripping unit. Additional auxiliary modules can be added (optional) to indicate switch position, fault tripping, shunt trip, under-voltage release, over-voltage release. The NG125L circuit breaker meets the following standards: IEC/EN 60947-2.
