MNS Low Voltage Drawer-out Type Switchgear up to 4,000A for Commercial and Industrial Electrical Distribution IEC 61439
MNS Drawer Type Low-voltage Switchboard
MNS system are suitable for applications in all fields concerning the generation, distribution and use of electrical energy, e. g., they can be used as: Main and sub-distribution boards for energy and Motor current supply of Motor Control Centers
• Utility companies
• Power plants
• Oil refineries
• Off-shore drilling platforms
• Production facilities
• Buildings for other than dwelling purposes.
The MNS system is full complied with GB7251.1, IEC 439-1, EN 60 439-1, VDE 0660 part 500, BS 5486 Part 1 and UTE 63-410
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.
