Industrial Cables Single Core Fixed Wiring Cable
2491B to BS 7211(New BS EN 50525-3-41)
Application and Description
2491B to BS 7211(New BS EN 50525-3-41) flexible cable are used in panel, conduit and general fixed wiring applications where there is a requirement for flexibility during installation and in the event of fire, a need to minimize the risk from smoke and toxic fumes but where circuit integrity is not required. Not suitable for wet or immersed applications. 2491B is equivalent to harmonized code H05Z-U/H05Z-K.
