Fully IEC verified and tested low voltage switchgear assembly

MNS is ABB's low-voltage switchgear and controlgear assembly for power distribution and motor control. The MNS design is verified in accordance with the latest IEC standards, IEC 61439 -1/-2 and IEC TR 61641.  MNS switchgear assembly is of scalable design, enabling ABB to supply integrated solutions for today's challenging business environment. It is the leading technology combining maintenance-free frame structures and busbars, a fully modular construction and the capability to integrate feeder, motor starter, variable speed drives, power factor compensation etc. and even UPS technologies in safety focused, space saving and project-optimized manner.

Main benefits

  • Unmatched safety for protection of personnel and plant exceeding standard requirements
  • Reduced operational expenditure through maintenance free bus bar design
  • Increased availability through modular design using withdrawable, plug-in, compact or fixed functional units
  • Reliable, flexible and scalable fully accessible from the front
  • Space saving design with compact, back-to-back or duplex arrangement
