Basic frame
Description
The basic frame of MALCOpower 2000 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 3 widths
The 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:
400 mm.
600 mm.
1000 mm.
formed by combining two frames, one 400 mm and the other 600 mm deep.
Basic frames are available in three widths:
700 mm.
900 mm (Mw type).
1200 mm (for Masterpact MT40b, MT50 and MT63).
The width of a 700 mm column may be increased by adding one or two extensions (200 mm or 400 mm).

MALCOpower 2000 a high-dependability system for trouble-free operation of your installation
System is designed to provide a high level of reliability and safety, thus reinforcing the protection of life and property. Offers all the essential guarantees: compliance with international standards, notably IEC 60439-1, IEC 60529 and IEC 60947. Compliance with local standards, thus meeting local legal and technical requirements. A system implementing tested Schneider switchgear components to ensure optimum operation.
Internal equipment
The switchgear components contained in the columns are installed on mounting plates. The combination of a mounting plate with switchgear components is called a functional unit.
Functional units are defined by standard IEC 60439-1 as a part of a low-voltage switchgear and controlgear assembly comprising all the electrical and mechanical elements that contribute to the fulfilment of the same function. The height of a functional unit is defined by the number of 50 mm modules it occupies.
A column may contain 40 modules, each 50 mm high.
Selection and layout of the electrical switchgear components are subject to a rigorous method designed to enable switchboard definition without risk of error.
mounting of Legrand DPX circuit breakers:
DPX circuit breakers are mounted on horizontal plates and are available in two
versions:
fixed,
withdrawable.
mounting of other switchgear components:
Circuit breakers, contactors, thermal relays, variable-speed drives and starters are installed on vertical mounting plates.
The circuit breakers for vertical mounting plates are available in three versions:
fixed,
disconnectable,
withdrawable.
All circuit breakers may be installed with their controls:
behind the door,
on the door. |

Safety
Drawers are built in compliance with international standard IEC 60439-1 which regulates the drawer extraction and locking system.
The connection mechanism is designed to allow the drawer to be set to any of thefour positions presented below. The degree of protection of the switchboard is
Maintained in all positions (connected, test, disconnected and drawer removed).
This is made possible by the door that can remain closed in these four positions.
Columns for power factor correction type Dc
The equipment for automatic compensation of reactive energy is installed in columns
700 mm wide, containing:
fixed set of busbars.
functional mounting plates equipped with Dry Type capacitors and
contactors for capacitor control. |

Reactive energy regulator.
The above equipment may be integrated in a distribution switchboard or remain
separate.
