(BS 6360 Cl-1/IEC 60228 Cl-1) 6491B (BS 7211) Copper Core Industrial Cable

This cable is mainly used for internal wiring in distribution boards and switchboards, generally installed in ducts for internal wiring of equipment with an operating temperature of 90°C. It is suitable for use in public places (e.g. government buildings, etc.) where fumes and poisonous gases may cause life-threatening injuries and damage to equipment. This cable does not produce corrosive gases when burned, which is especially important for electrical equipment. 6491B is equivalent to the EC standard H05Z-U/H07Z-U/H07Z-R.
