Secondary switchgear MNS

arc protectionlow-voltagefor motors

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 • Main features  • Fully certified to IEC 61439-1/-2 low-voltage switchgear assembly up to 690V, up to 6300A, up to 100kA • Passive arc protection criteria 1 to 7, tested acc. IEC TR 61641 Ed.3 criteria 1 to 7, arc proof certified up to 690V, 100kA • Modular construction, extendable at both ends and reconfiguration capabilities • Ease of operation with closed doors and single handle operation • Segregation up to form 4b  •
