The Schneider Electric LS Switch 18855 is a circuit breaker Acti 9 NG125L with 50 kA (IEC/EN 60947-2). It is 2-pole, has a rated current of 63 A, and a D 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 middle position of the switch lever and a red mechanical display on the front of the device. A test button to check the tripping mechanism is included. The supply can be connected from above or below. The switch features a snap-action mechanism for low-wear contact switching and utilizes a thermal-magnetic technology for the tripping unit. Additionally, stackable auxiliary modules (optional) are available, allowing for the indication of switching positions, fault trippings, operational current triggers, undervoltage triggers, and overvoltage triggers. The NG125L circuit breaker complies with the standards IEC/EN 60947-2.
