MNS2.0 combined low voltage switchgear
I want to make an inquiry
MNS2.0 combined low-voltage switchgear is a new type of combined low-voltage switchgear developed and developed on the basis of the cooperation with Swiss ABB (China) Investment Co., Ltd., introducing its technology and widely absorbing the advantages of similar products at home and abroad. The device is suitable for AC 50Hz, rated working voltage 400V and below, can fully meet the various types of application requirements of the market, as a variety of power generation, transmission, distribution, power conversion and power consumption control equipment, can be widely used in the main , auxiliary power cabinets, power distribution cabinets, motor power supply and motor control centers, open loop or closed loop control system cabinets and power systems, petrochemical, industrial and mining enterprises, utilities, municipal engineering, commercial buildings and other low-voltage power distribution systems.
The switchgear is fully compliant with the national standard GB7251.1 and the international standard IEC60439-1.
◆The frame structure adopted by MNS2.0 is highly flexible, and the structure does not need to be repaired once assembled. Different standard components can be installed in the cabinet to meet various application requirements. The dry system consists of a modular design with electrical components. This optimized structural design meets the requirements of various components and can meet different working environments to achieve the corresponding level of protection.
◆MNS2.0 system has more advantages than traditional products:
● Compact structure, saving the volume of the cabinet;
●The cabinet can be arranged back to back;
●The distribution circuit is economical, all ABB components are selected to facilitate the design of engineering designers.
● Full range of standardization;
●The cabinet can be designed according to the different requirements of work and environment;
● Freely install different types of functional components in a cabinet, such as: fixed components and withdrawable components;
● Equipment update is easy to improve;
● Equipment running continuity and reliability;
● The personal safety of the operators is guaranteed.

Normal use environmental conditions
◆MNS2.0 low voltage switchgear is suitable for indoor electrical equipment installation. The protection level of switchgear can reach IP54.
◆ Ambient temperature:
Shortest time maximum temperature: +40 ° C;
24-hour maximum average temperature: +35 ° C;
Minimum temperature: -5 ° C;
◆ The climatic environment during normal operation is in accordance with IEC60439-l, EN60439, VDE0660 part 500. The relative humidity of the surrounding environment is 50% at 40 °C.
◆ The conditions of the installation location of the switchgear should meet the requirements of the corresponding standards. In the case where condensation will occur, ventilation or heating measures will be taken in the switchgear to prevent condensation.
◆ If the switchgear is installed above 2000 meters above sea level, the equipment should be derated.
◆ Exceeding the above conditions of use, when the user has special requirements, it can be specially negotiated with the manufacturer.
