NHXMH-J / NHXMH-O is a 300/500 V halogen-free installation cable with copper conductors and cross-linked polyethylene (XLPE) insulation, designed for fixed electrical installations in residential, commercial and public buildings.
The cable is suitable for fixed installation on or under plaster, in dry and wet rooms, and in concrete, excluding shaken, jolted or tamped concrete. Its halogen-free construction helps reduce corrosive gas emissions in the event of fire.

NHXMH-J / NHXMH-O Cable Range
Available in selected single-core and multicore
configurations. Cable dimensions, weights and
electrical properties depend on the selected
cross-section and conductor construction.
* CPR classification depends on the exact cable variant
and Declaration of Performance (DoP).
Dimensions and weights are nominal manufacturer values.
