YMz1K mbzh (LSZH) cable

Our YMz1K mbzh and our YMz1K mbzh flex are low smoke zero halogen cables (LSZH) suitable for low voltage (0.6/1kV) applications requiring compliance with Dutch national standard NEN1010. This includes above-ground installations in public buildings and environments requiring the minimisation of smoke and corrosive gas emission in the event of fire. This product range is suitable for fixed installation with clamps, saddles and cable cleats. It can also be used in certain conduits, trays and ducts.

Our range of YMz1K mbzh is tested and accredited by the KEMA Laboratories in The Netherlands to KEMA K42C-1-5.

The more flexible class 5 version our YMz1K mbzh cable range offers a minimum bending radius over 6 times its overall diameter versus 12 times for the class 1 and class 2 versions.
