The Acti 9 NG125N circuit breaker has a rated current of 80 A and a C characteristic. The operating voltage is 380-415 V AC, and the insulation voltage is 690 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 a red mechanical indicator on the front of the device. A test button is available to check the tripping mechanism. The power supply can be connected from the top or bottom. The jump switching feature allows for low-wear contact switching. The technology of the tripping unit is thermomagnetic. Additionally, stackable auxiliary modules (optional) are available, allowing for the indication of switching position, fault tripping, operational current tripping, undervoltage tripping, and overvoltage tripping. The NG125N circuit breaker complies with the IEC/EN 60947-2 standards and is VDE certified.
