Cu/LSZH/LSZH 6241b cable are the electric cables referred to thermosetting insulated and thermoplastic sheathed cables for voltage 300/500V electric power and lighting and having low emission of
the smoke and corrosive gases when affected by the fire.
624-B refers to thermosetting insulated and sheathed cables, single-core 6241B, flat twin-core 6242B, flat 3-core 6243B, with circuit protective conductor (CPC) 300/500V. The conductor is annealed
copper conductor of class 1 or class 2. The maximum size is up to and including 16 mm². We supply the cables according to BS7211.

Application Of 6241B LSZH Single Cores +Earth Cable
6241 B LSZH cables are widely used in domestic and industrial power or lighting system. They normally installed in conduit and trunking or can be surface nounted if used as earth cable. They are
good options for using in public buildings to reduce the threat to life and equipment cased by smoke and toxic fumes. They can't be installed incontrete without mechanic protection.
