6491X/6491X HR to BS 6004(New BS EN 50525-2-31)
Application and Description
6491X/6491X HR to BS 6004(New BS EN 50525-2-31) cables are designed for use as fixed wiring in domestic,
Industrial power and lighting applications such as light fittings, appliances, switchgear and control gear, they
can be used in conduit or trunking or surface mounted when used as an earth. 6491X is equivalent to H07V-
U/H07V-R/H07V-K.The heat- resistant version is ideal for use in installation which are subject to direct contact
with high temperature equipments (e.g. varnishing machines and drying towers etc.).
