The Schneider Electric Circuit Breaker 18636 is an Acti 9 NG125N circuit breaker with a breaking capacity of 25 kA (IEC/EN 60947-2). It is 2-pole, has a rated current of 32 A, and a C characteristic. The operating voltage (Ue) is 380-415 V AC, and the insulation voltage (Ui) is 690 V AC. It protects the circuit against short-circuit and overload currents. The tripping is indicated by the central 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 included. The supply can be connected from above or below. The jump switching allows for low-wear switching of the contacts. The technology of the tripping unit is thermomagnetic. Additionally, stackable auxiliary modules (optional) are available, which enable the display of switching position, 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.
