Product Description
Low Voltage Withdrawable Switchgear Series(MNS&GCS&GCK)
MNS low voltage withdrawable switchgear is assembled low voltage switchgear equipment and meets technical standards IEC439,GB7251, JB/T9661, UTE63-410 and so on.MNS series low voltage switchgear include fixed type and withdrawable type technology, withdrawable type technology can be divided into steel plate structure and plastic structure technology.MNS series adapt to various power supply and distribution needs and can be widely used in power plant, nuclear power station, marine, petroleum, mine ,etc.as well as distribution systems of various industrial and mining enterprises.MNS series product has many obvious characteristics and advantages, such as compact design, the structure with strong commonality, use standardized modular design and technological superiority.
I. Range of Use & Purpose The switch cabinet is applied to the distribution system in the power plants, high-rise buildings, chemical industry, and petroleum, metallurgy and textile industries. In the large power plants and highly automated petroleum and chemical industries that require connecting with computers, it is used, as a complete low-voltage distribution equipment, for power distribution in the power generation and distribution system with three-phase AC frequency 50(60)Hz, 380V(400)(600) and rated current up to and including 4000A, and motor centralized-control and reactive power compensation.
