HO7Z-R 450/750V Low Smoke Cable
 |  |  |
APPLICATIONS OVERVIEW
The 6491B low smoke halogen free cable is most suited for use in conduit and for fixed protection installation.
They can be used in lighting installations, switch and control gear and also in appliances.
These fittings require a higher temperature threshold from cables which the 6491B is suitable for.
The low smoke zero halogen outer sheath is ideal in applications where fire, smoke, emissions and toxic fumes would create a potential threat.
The cable features a stranded plain annealed compacted circular copper conductor and a LSZH outer sheath.
The cable is available in brown, black, grey, blue, green/yellow, white, orange, turquoise, violet or Pink.
