MNS low-voltage withdrawable switchgear

Overview of electric drawout switchgear :

The MNS system is a product that our company introduced the manufacturing technology of ABB of Switzerland. It is a factory-assembled low-voltage switchgear device. The technical standards comply with GB7251.1, IEC439-1, VDE0660 Part 500, BS5486 Part 1, UTE63-410. As a marine product, it also complies with the LIOYD’S REGISTER marine standard.

The MNS system low-voltage switchgear includes fixed technology and drawer technology. The selected materials are divided into steel plate structure technology and plastic structure technology. The latter technology level has reached the international level in the 1990s. The MNS system can adapt to various power supply and distribution needs and can be widely used in various industrial and mining enterprise power distribution systems such as land use, power stations, nuclear power stations, ships, and oil platforms.
