MNS 3.0 (ABB Technology)

 

The MNS3.0 (ABB Technology) is a type-tested switchgear assembly in accordance with IEC 60439-1 and 61439. MNS3.0 offers the best solution for all the applications where safety, reliability, reduce maintenance and top performances are fundamental.
The realization of both flexible and compact solutions was possible thanks to a strong application of the modularity concept either for the mechanical or electrical development together with the use of unified components.
The huge ABB know-how about design and construction of low voltage systems for its customers are the result of a mixed experience coming from local and global markets.
Main features of MNS platform switchgears are flexibility together with high technology content; through this mix it is possible to satisfy all customer's requests.
Safety is one of the key points for the development of ABB switchgears, in fact all the MNS can be supplied in “Arc proof version” up to 100 kA.
