EMNS LV withdraw-able switchgear is manufactured by consulting MNS LV switchgear of ABB Switzerland, and synthetically improved.
It is applicable to systems with AC50-60Hz, rated voltage up to 660V and rated current up to 4000 A.
Type tested, conforms to IEC60439-1, GB7251 standard and CCC certified.
Space saving. Cabinet contains different function units within a smaller footprint, the space on ground would save up to 33% over current solutions.
Universal and flexible. By using the 25mm module c-shape profile, it meets the requirements of various structural types, protection grade and operation environment.
Modular construction, multifunctional, reliable and safe performance.
Arc proof certified up to 690V, 100KA.
Easy to install and operate, maintenance free.
Optimum protection for personnel and plant.
Designed to maximize the prevention of arc fault, and can ensure to crush out the arc in the shortest time.
Adopt high strength anti-flaming type engineering plastic pack in large quantity to prevent burning and to increase safety.
All frames and inner isolation plates are galvanized and passivated.
Door panels and side plates are treated by electrostatic spraying.
Each functional unit can operates relatively independently, and that of out-going lines can be installed with at most 36 circuits.
Different types of functional components can be freely installed in a cabinet,such as fixed components and extraction components.
Cabinet can be arranged back-to-back.
