General
MNS LV withdrawable switchgear is manufactured by standard module
through consulting MNS series low voltage switch cabinet of
Switzerland ABB Company and synthetically improved. The device is
applicable to the system with AC 50Hz, rated working voltage 660V
and below, used as a control device for various power generation,
transmission, distribution, power transfer, and power consumption
devices. It is widely used in low voltage distribution systems of
the various mining enterprises, tall buildings, and hotels,
municipal construction, etc. Besides the general land use, after
special disposal, it also can be used for marine petrol drill taken
platform and nuclear power station. The device accords with
international standard IEC439-1 and national standard GB7251.1.
