6242B 4.0mm² LSZH Twinand Earth Cable – White (100m Drum)

High-Capacity 4.0mm LSZH Twin & Earth Wiring
Electrical contractors choose the 6242B 4.0mm cable because it delivers high-capacity power while maintaining maximum fire safety. Specifically, this cable utilizes Low Smoke Zero Halogen (LSZH) technology. Consequently, the outer sheath produces minimal smoke and zero corrosive gases if a fire occurs. This feature is vital because it ensures safer evacuation routes in high-occupancy buildings like schools or hospitals.
Engineered for High-Power Applications
Furthermore, the 4.0mm² cross-sectional area makes this cable perfect for demanding power circuits. Specifically, professionals use it for wiring electric showers, high-wattage cookers, and radial power circuits. In addition to its high load capacity, the XLPE insulation supports operating temperatures up to 90°C. Because of this thermal stability, the cable performs reliably even under heavy electrical loads.
