The Acti 9 NG125N circuit breaker has a rated current of 100 A, a C characteristic, and an operating voltage of 380-415 V AC. It protects the circuit against short-circuit and overload currents. The tripping is indicated by the middle position of the switch lever and by a red mechanical indicator on the front of the device. A test button for checking the tripping mechanism is included. The supply can come from the top or bottom. There is a spring mechanism for low-wear switching of the contacts. The technology of the tripping unit is thermomagnetic. Additionally, attachable auxiliary modules (optional) allow for the display of switching status, fault tripping, operational current tripping, undervoltage tripping, and overvoltage tripping. The NG125N circuit breaker complies with the standards IEC/EN 60947-2 and is VDE certified.
