MNS outdoor industrial main switchgear is a three-phase AC frequency of 50 (60) Hz, rated working voltage 380V (400), (600V), rated current below 4000A power generation and power supply system.
MNS low-voltage withdrawable switchgear (hereinafter referred to as switchgear) is a fully assembled low-voltage switchgear with flexible structure. Modularity, multi-function, reliable and safe performance. Applicable to metallurgy, petroleum, chemical, industrial and mining enterprises and infrastructure and other fields, as a three-phase AC frequency of 50 (60) Hz, rated working voltage 380V (400), (600V), rated current below 4000A power generation and power supply system In all low-voltage systems such as power distribution, centralized motor control and so on.
The switchgear has undergone a comprehensive type test and passed the national compulsory product 3C certification. This product complies with GB7251.1 "Low-Voltage Switchgear and Control Equipment", IEC60439-1 "Low-Voltage Switchgear and Control Equipment" and other standards.
1. The ambient air temperature does not exceed 40℃, and the average value measured within 24h does not exceed 35C, and the minimum air temperature in the weekly chart is -5℃,
2. The altitude of the installation site does not exceed 2000m
3. The surrounding air is not significantly polluted by dust, smoke, corrosive and soluble gases, steam or salt spray:
4. Atmospheric conditions: The air is clean, and the relative humidity should not exceed 50% when the maximum temperature is +40℃. At a lower temperature, a higher relative humidity is allowed. For example: the relative humidity is 90% at +20°C. However, it should be considered that due to temperature changes, moderate condensation may occasionally occur;
5. When the equipment is installed, the inclination from the vertical does not exceed 5°;
6. The equipment should be installed in a place where there is no severe vibration and impact.
The product design fully takes into account the requirements of the majority of power users and design departments, and can meet the needs of the ever-developing power industry for centralized control, convenient installation and maintenance, and shortening of incident handling time. It is safe, economic, reasonable and reliable. The product has the characteristics of strong repairing power, high breaking capacity, good dynamic stability, flexible electrical scheme, convenient combination, strong series and practicability, and novel structure. It is an updated product of domestic low-voltage fixed switchgear. At the same time, it can be combined with the drawer cabinet for mixed use.
