General features of the series
With the new Protecta Plus system, ABB has developed a new and personalised
series of MCB distribution boards which can be expanded over time. The wide
internal accessibility ensures a quick and easy approach to the electrical components
assembly. The neutral and earth bars positioned on the inner sides of the
distribution board are completely isolated to ensure better safety for users.

A comprehensive range
The range consists of distribution boards for wall
mounting in six heights from 590 mm to 1360
mm, 450 mm width and depth starting from
125 mm, ensuring the development of multiple
solutions. Protecta Plus system is easy to design,
quick to assemble and reliable to apply.

Ease of wiring
With the new mounting concept, Protecta Plus
offers great levels of flexibility and accessibility
for installation and wiring. The internal module
can be easily removed allowing the wiring of
different equipment outside the distribution board.
This solution allows for an easier installation with
more rapid production times.
Maximum accessibility
Thanks to the particularly large opening angle of
the door, Protecta Plus offers the possibility to
have optimal access to the distribution board,
especially in case of maintenance. The perfectly
reversible doors can be installed with right
or left opening.
