Either Okken or MB301 switchboards enable
optimum and rational use of all Schneider Electric’s
low voltage products. The complete range satisfies all
electrical distribution requirements, from generation
to motor control and final distribution.
Moreover, several versions are available (front and
rear access, fixed or withdrawable drawers, degree of
protection up to IP44) to satisfy all the requirements
and limitations as far as space and location are
concerned, due to marine use. They have been used,
with full satisfaction of the shipowner, in all types of
applications, from oil-tankers to cruise ships.
