Schneider MNS series Low-voltage draw-out switchgear panel
Descriptions
MNS low-voltage draw-out switchgear panel is a modular, multi-functional low-voltage distribution cabinet type, suitable for a variety of industrial and infrastructure fields, such as power plants, substations, petrochemical, metallurgical steel, as well as residential areas, high-rise buildings and other occasions. With different famous brand, ABB, Siemens ,Schneider etc , the MNS series Low-voltage draw-out switchgear is compact in design and highly flexible, able to accommodate more functional units in a smaller space, and has strong structural versatility and flexible assembly .
The rated insulation voltage of Schneider MNS series Low-voltage draw-out switchgear panel is 660V, the rated working voltage is 380V, the maximum working current of the main bus can reach 6300A, the short-time withstand current is 100kA, and the peak withstand current is 220kA. In addition, Schneider MNS series Low-voltage draw-out switchgear panel meets a number of national and industry standards, such as GB7251.12, GB/T15576, JB/T9661, and in line with international standards such as IEC61439
Working condition
●The Environment air temperature shall not be higher than +40°C, not lower than -5°C, and the average temperature within 24h shall not be higher than +35°C;
●For indoor installation and use, the altitude of the use place shall not exceed 2000m;
●The relative humidity of the surrounding air should not exceed 50% when the maximum temperature is +40°C, and a larger relative humidity should be allowed at a lower temperature (such as 90% when +20°C), taking into account the effect of condensation that may occur occasionally due to changes in temperature;
●The inclination of the vertical plane shall not exceed 5° when installation;
●The equipment should be installed in a place without violent vibration and impact, and not enough to corrode the electrical components.
Product structure Characteristics
●Compact design: to accommodate more functional units in a smaller space;
●Strong structure versatility, flexible assembly: 25mm as the modulus of the C profile can meet the requirements of various structural forms, protection levels and use environment;
●Standard module design: can be composed of protection, operation, transition, control, adjustment, indication and other standard module, users can choose according to the needs
●High technical performance: the main parameters reach the international technical level;
●Compressed site: compact, which can greatly compress the storage and transportation of pre-made sites;
●Easy assembly: no special complexity is required.
