Introduction

The MNS R main low voltage distri-
bution switchgear with rear access
had been studied for installation in
large electrical plants, such as petro-
chemical plants, steel works, rolling
mills, power stations, oil rigs, ships,
etc.
The service conditions on these plants
are often extremely severe: the high

currents involved and the effective
short-circuit levels require high per-
formances switchgears. Furthermore,
must be guaranteed personnel safety,
service continuity, easy inspection,
maintenance, erection and installa-
tion. Easy extension applications as
well as compact overall dimensions
are a must. The Power Center MNS
R switchgear fully complies with all
these requirements. In addition to
that, due to a perfect integration with
all the latest generation of ABB appa-
ratus, it easily meets all market re-
quirements.
