Finland-based Schneider-Electric NB (Strömfors) has developed a reputation for having the most sustainable applications in its market. Anything they developed would have to meet the international electrical standard IEC 60670-1, which says the materials used in the wall boxes have to pass a Glow Wire Flammability Index (GWFI) 850°C testing (IEC 60695-2-12) at the application thickness, and 960°C at 2mm. By replacing a potentially harmful material, Schneider-Electric improved production efficiencies while solidifying its leadership position as an ethical, eco-friendly producer of high-quality electrical supplies.
