The MX range provides a versatile, fixed-configuration solution for supporting conductors across a wide variety of panel designs.

Available in both three-phase and three-phase + neutral versions, these supports achieve Icw fault ratings up to 65 kA for 3 s.

Their consistent geometry and robust glass-reinforced polyamide 6.6 construction make them ideal for standardising designs across multiple assemblies.

Metric and imperial options suit both bare and insulated copper conductors, while different phase centres and bar configurations allow easy integration into new or retrofit installations.
