The Acti 9 NG125L circuit breaker has a rated current of 80A and a B characteristic. The operating voltage is 380-415V AC, and the insulation voltage is 690V 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 display on the front of the device. A test button for checking the tripping mechanism is available. The switch can be fed from the top or bottom and features a spring mechanism for low-wear contact switching. The technology of the tripping unit is thermomagnetic. Additionally, stackable auxiliary modules (optional) are available, allowing for the display of switching status, fault tripping, operating current tripping, undervoltage tripping, and overvoltage tripping. The NG125L circuit breaker complies with the IEC/EN 60947-2 standards. EAN: 3303430187677.
