The Acti 9 NG125L circuit breaker has a rated current of 63 A and a B 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 switching lever and a red mechanical display on the front of the device. A test button for checking the tripping mechanism is available. The supply can be connected from the top or bottom. The circuit breaker features a snap-action mechanism for low-wear switching of the contacts and uses a thermal-magnetic tripping unit. Additionally, stackable auxiliary modules (optional) are available, allowing for the display of switching positions, fault trippings, working current triggers, under-voltage, and over-voltage triggers. The NG125L circuit breaker complies with the standards IEC/EN 60947-2. EAN: 3303430187660.
