SYSTEM LV2002 Power Center is a LV distribution switchboard particularly suitable for applications requiring high performance and a high level of reliability. They are generally installed downstream the MV/LV transformers or generator groups and contain the main and distribution circuit-breakers of the LV plant.
They consist of standardized section based on a easy-to-fit modular design permitting to suit any plant configurations, electrical diagrams and installation sites.
The wide range of sections and the availability of different versions which ensure both front and rear access, offer different solutions satisfying any need in terms of installation and space requirements. Switching and regulation operations on the equipment, as well as the access and routine maintenance of the switchboard can be carried out in maximum safety for personnel and with no danger of accidental contact with live parts.
Thanks to their versatility and high performance, SYSTEM LV2002 switchboards can be used in power production plants, industrial plants, on installation board and anywhere else are required:
SYSTEM LV2002 switchboard has been designed and built respecting the main international and national standards:
SYSTEM LV2002 switchboards are subjected to the type tests foreseen in the standards. On request the documentation from national and international laboratories are available.
All the switchboards are subjected to the routine tests foreseen in the standard:
SYSTEM LV2002 section consist of standardized elements whose mode of installation enables operations of modification and/or adaption to be performed in complete safety, without particular settings or tools. The supporting structure has four functional spaces:
These four 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).
