SYSTEM MCC type LV 2004 is a modular system of withdrawable units for the supply, control and protection of law voltage motors. Thanks to their versatility, they can easily be adapted to suit any plant configuration, electrical diagram and installation site. The fact that the switchboard is completely accessible from the front means that it can be installed against a wall or back to back with consequent space-saving. All the operations involving insertion and removal of the withdrawable unit as well as those of accessing the supply and outlet cable cupboards can be done from the front, without any danger of coming into contact with any live parts.
Thanks to their simple and robust modular structure, these switchboards can be used in power production plants, industrial plants, on-board installations and anywhere else they are required:
SYSTEM LV2004 switchboard has been design and built respecting the main national and international standards:
LV2004 SYSTEM switchboards are subjected to the type tests foreseen in the standards. On request the documentation from national and international laboratories is available.
All the switchboard are subjected to routine tests foreseen in the standard:
SYSTEM LV2004 section consists of standardized elements whose mode of installation enables operations of modification and/or adaptation to be performed in complete safety, without particular settings or tools. The supporting structure has three functional spaces:
These three spaces are enclosed in a metallic casing, whose walls provide protection against contact with live parts and the penetration of liquid and solid foreign bodies (CEI EN 60529).
The modular design of the switchboard guarantees:
