LSOH thermosetting core insulation type EI5

Application and Description

6491B to BS 7211 (New BS EN 50525-3-41 cables are designed for fixed wiring purposes in domestic and industrial power/lighting applications. They can be used in trunking or conduit, or may be surface mounted when used for earthing. And 6491B to BS 7211 (New BS EN 50525-3-41) cables are generally in areas (such as public and government buildings) where smoke and toxic fumes may cause a threat to life and equipment. 6491B to BS 7211 (New BS EN 50525-3-41) cables produce no corrosive gasses when burnt and which is particularly important where electronic equipment is installed. 6491B is equivalent to harmonized code H07Z-U/ H07Z-R/H07Z-K.
