MNSLow voltage withdrawable switchgear
MNS low-voltage withdrawable switchgear is a fully assembled low-voltage switchgear with flexible structure, modularity, and multifunctionality. Suitable for use in fields such as metallurgy, petroleum, chemical, industrial and mining enterprises, and infrastructure, as a low-voltage system for distribution and centralized control of motors in power generation and supply systems with a three-phase AC frequency of 50 (60) Hz, rated working voltage of 380V (400V, 660V), and rated current below 4000A.
The MNS low-voltage switchgear produced by our company has undergone type testing and passed mandatory product 3C certification. This product meets the standard of GB7251.2 Low Voltage Switchgear and Control Equipment.
Structural characteristics of MNS low-voltage switchgear
The design of MNS low-voltage switchgear products fully considers the requirements of power users and design departments, and can meet the needs of the continuously developing power industry for centralized control of increased capacity, convenient installation and maintenance, and shortened accident handling time. It is safe, economical, reasonable, and reliable. The product has the characteristics of strong connection ability, high breaking ability, flexible electrical scheme, convenient combination, strong series and practicality, and novel structure. It is a substitute product for low-voltage fixed switchgear in China, and can be combined with drawer cabinets for mixed use.
Basic structure: The structure of the MNS low-voltage switchgear cabinet is composed of assembled profiles. Due to the use of locking self tapping screws and 8.8 grade high-strength bolts for connection, the cabinet has high accuracy, good rigidity, and separation of the exterior and interior of the cabinet.
