This box or cabinet holds all elements for the protection of the general power line and marks the beginning of the clients installations.

 
It's made with a self extinguishing and sealable isolated enclosure which contains the connection terminals and fuse holders (BUC).

 
In case there are several low voltage general supplies and as a consequence more than two fuse enclosures are needed, we will use protection panels with tripolar vertical fuse bases (CP/BTVC).

 
The protection and distribution panels will be composed of BTVCs fixed with screws to a copper busbar system, always installed inside insulated enclosures.

 
They'll be fixed to the wall through a frame, which will be screwed to the busbar.
