SWITCHBOARD COMPOSITION

INSTRUMENTATION AND PLC PANEL

The instruments and plc panel are accessible through openable panel provided of lock.
The equipments can have fixed inside the cubicle or directly on the door or on special modular panels.
The panels have the following modularity: 1Mod =100mm
The possible measures go from 100mm to 2200mm.



MCC WITH FRONTAL ACCESSIBILITY

CHARACTERISTICS
This type of closet is used in applications where the switchboard can be placed to the wall or behind another switchboard.
This structure makes the copper bar system accessible after the istallation so that to allow the insertion of new uses and to facilitate the periodic maintenance.



A - Vain gone up again additional for connection to the general interrupter.
B - Vertical omnibus Bars on every column
C - Protection in insulating material
D - Useful Depth of wiring
E - Terminal block of connection
F - Superior vertical bars
G - Stirrups for fixing cable

MCC WITH BACK ACCESSIBILITY

CHARACTERISTICS
This type of closet is used in applications where the switchboard can be accessible from the front and from the back.
In this structure the copper bar system is placed on the back side making the front side totally exploitable.
In this case the cable vain are used only for the external connections to the switchboard allowing an optimization of the encumbrances.



A - horizontal principal omnibus Bars
B - vertical omnibus Bars on every column
C - useful Depth of wiring
D - Terminal block of connection
C - Stirrups for fixing cable
F - Segregation vain cables
