The arc protection system determines the light exceeding the set value by the intensity of light (illuminance). In general, the illuminance of offices and conference rooms is 200-750 Lux, the illumination of drawing rooms and computer rooms is 300-1500 Lux, and the direct sunlight in summer is only 10,000 Lux. In the event of an arc fault, the illuminance can reach 100KLux, far exceeding the ordinary light source. The arc protection system is generally recommended to be set at around 30KLux, which can shield all daily interference sources. In addition, the illuminance of the electric welding can reach the range of the arc protection setting value, and the electric welding should not be used within 7 meters of the switch cabinet with the arc protection system. If the project requires it, you must temporarily add a visor or temporarily exit the arc protection system (exit the trip outlet protection platen).
