6491B to BS 7211 (New BS EN 50525-3-41)

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.
