Medium Power Range

For 125, 160, 250, 400, 630 & 800A applications the Mempower MP system is the natural extension to the LP range. Assembly of the pre-fabricated units is made easy with the housing offering IP4X protection as standard (IP54 on request).

The aluminium profile with interlocking, flame retardant moulded covers provide both support and segregation for the five conductors and include tapping outlets every third of a metre. The fifth bar can be used as a clean earth when specified, in which case the aluminium profile provides a separate protective earth.

A full size neutral is incorporated.

A wide range of metalclad tap-off units including switch-disconnectors, fuse units, MCCBs, fused combination switches and MCBs are available along with a large selection of angles and components.
