Circuit breaker Acti 9 NG125LMA, 50kA (IEC/EN 60947-2). 3-pole, nominal current 40A, MA characteristic, operating voltage (Ue) 380-415V AC, insulation voltage (Ui) 690V AC. Protection of the circuit against short-circuit currents. Protection of the circuit against overload currents. Tripping is indicated by the middle position of the switch knob and by a red, mechanical display on the front of the device. Test button for checking the tripping mechanism. Power supply from above or below. Snap action for low-wear switching of the contacts. Technology of the tripping unit - thermomagnetic. Additional auxiliary modules that can be added in series (optional) - display of switch position, fault tripping, shunt release, undervoltage release, overvoltage release. The NG125LMA circuit breaker meets the following standards - IEC/EN 60947-2.
