Low-voltage Draw-out Switchgear
MNS2.0

Product Introduction

MNS 2.0 is a type tested assembled low-voltage switchgear (TTA) developed and designed by ABB, which complies with standards such as IEC61439 and GB7251.
The installation and connection of the system are carried out in accordance with the IEC364 and DIN VDE0105 standards. Suitable for all places where electricity is generated, distributed, and used.
The MNS 2.0 assembled low-voltage switchgear system has proven its value in the world market after years of use. The entire system fully considers future development opportunities
It can avoid the risk of being eliminated due to technological development.
The cabinet structure adopted by the MNS 2.0 system has a high degree of flexibility, and once the structure is assembled, it no longer needs maintenance. Different standard components can be installed inside the cabinet to meet various usage requirements. Due to the combination design of the entire system, including the electrical structure, this optimized structural design meets the requirements of various components and is suitable for different working environments, achieving corresponding protection levels.
