Main Technical Indicators

Blokset switchgear consists of four different compartments, they are:

1.    Bus compartment

2.    Component compartment

3.    Outgoing cable compartment

4.    Accessory compartment

Depth and width

Blokset series can form various switchgears with different depths and widths through the combination of basic frames and extended frames.


There are three different depths for basic frame:

1.    400mm(applied for horizontal busbar whose maximum current is 1600A.)

2.    600mm(common used frame)

3.    1000mm(add 400mm (depth) on the basis of 600mm(depth) basic frame)


Different width

1.    500mm (Mw type)

2.    600mm (Mx type/U type/D type)

3.    700mm (D type/Dc type/Mf type/Ms type)

4.    900mm(Mw type)

5.    1200mm (D type, MasterpactMT40b/50/63)

Extended cabinets can be installed to the both sides of the basic cabinet if necessary (200 to 400mm).
