Overview: MNS-type low-voltage or complete switchgear (hereinafter referred to as low-voltage switchgear) is our company with China's low-voltage switchgear development trend in the selection of electrical components and cabinet structure improvements and re-registration of the product. The electrical and mechanical properties of the product fully meet the original MNS product technical requirements.
Scope of application: MNS type low voltage switch cabinet is suitable for the power supply plant, transformer substation, petrochemical industry, metallurgy steel rolling and other industrial enterprises and residential quarters, high-rise buildings and other places, the exchange 50-60Hz, rated working voltage AC 660V and below distribution system Of the energy replacement and consumption of equipment control purposes.
Use of environmental conditions:
1. Ambient temperature is not higher than +40 ℃, not lower than -5 ℃, and the average temperature within 24H is not higher than +35 ℃.
2. Atmospheric conditions, the air clean, the relative humidity at a maximum temperature of +40 ℃ not more than 50%, at a lower temperature allows a higher relative humidity, for example, +20 ℃ 90%, but should be taken into account Due to temperature changes, there may be accidentally appropriate filling condensate.
3. Altitude of not more than 2000 meters
4. This device is suitable for transport and storage at temperatures between -25 ° C and + 55 ° C, up to 70 ° C in a short time (up to 24 hours) at which the device should not be subjected to To any unrecoverable operation, and under normal conditions should be able to work properly;
5. If the above conditions of use can not be met, the user and the manufacturer should be negotiated;
6. When the device is suitable for offshore oil drilling platforms and nuclear power plants, should be signed technical agreement.
