The Acti 9 NG125N circuit breaker has a rated current of 40A, a C characteristic, and an operating voltage of 380-415V AC. It protects the circuit against short-circuit and overload currents. The tripping is indicated by the center 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 available. The power 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 utilizes a thermal-magnetic technology for the tripping unit. Additionally, stackable auxiliary modules (optional) are available, allowing for the indication of switch 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.
