The NEW Utility Control Centre

Rolla UCC
Rolla UCC

High Quality, Very competitive by design to BS EN 61439-2:2011

For many years Rolla have been supplying the system/panel building industry with High Quality Motor Control Centres, many of which are an important part of the UK Water Companies Framework Agreements.

With cost savings firmly in mind we drew on our experience in this market sector and developed the new Utility Control Centre, carrying out a full range of tests to verify the system to the new standard.

This highly competitive Motor Control Centre incorporates all the requirements of the industry while maintaining the high quality of build that Rolla is renowned for.

Available with individual droppers per section or as a shared dropper option.
