Product Description

Product Description

 

  The basic frame of a Blokset switchboard column is an assembly of prefabricated elements. These elements are available in a number of sizes and may be assembled

to form columns with different volumes.

Each column is made up of four distinct zones for:

1 busbars

2 switchgear components

3 cable connections

4 auxiliaries

3 depths and 6 widths

The Blokset range may be used to build switchboards of various depths and widths by combining basic frames and extensions.

Basic frames are available in three depths:

b 400 mm

b 600 mm

b 1000 mm:

v formed by combining two frames, one 400 mm and the other 600 mm deep.

Basic frames are available in three widths:

b 500 mm (Mw type)

b 700 mm

b 900 mm (Mw type).

b 1200 mm (for Masterpact NW40b/NW50/NW63).

The width of a 700 mm column may be increased by adding one or two extensions

(200 mm or 400 mm)
