IP40 GB7251 IEC439 MNS Switchgear 660V LV Panel Board

General

MNS LV withdrawable switchgear is manufactured by standard module through consulting MNS series low voltage switch cabinet of Switzerland ABB Company and synthetically improved. The device is applicable to the system with AC 50Hz, rated working voltage 660V and below, used as a control device for various power generation, transmission, distribution, power transfer, and power consumption devices. It is widely used in low voltage distribution systems of the various mining enterprises, tall buildings, and hotels, municipal construction, etc. Besides the general land use, after special disposal, it also can be used for marine petrol drill taken platform and nuclear power station. The device accords with international standard IEC439-1 and national standard GB7251.1.

Technical Parameters

1. Compact design: Contain more function units with less space.

2. Strong versatility for structure, flexible assembly. C type bar section of 25mm modulus can meet the demands of various structures and types, protection grades,s, and operating environments.

3. Adopt standard module design, which can be combined into protection, operation, transfer, control, regulation, measurement, indication, etc such standard units. Users can choose assembly according to requirements at will. Cabinet structure and drawer unit can be formed with more than 200 components.

4. Fine security: Adopt high strength anti flaming type engineering plastic pack in large quantity to effectively enhance the protective safety performance.

5. High technical performance: Main parameters reach the advanced level at home.

Technical Data

Working environment

• The ambient air temperature is not higher than +40℃, not lower than -5℃, and its average temperature within 24h is not higher than +35℃.
• Atmospheric conditions, clean air, relative humidity does not exceed 50% when the highest temperature is +40℃, higher relative humidity is allowed at lower temperatures, for example 90% at +20℃, but temperature changes should be taken into consideration , It is possible to occasionally produce moderate condensation.
• The altitude does not exceed 2000m.
• This device is suitable for the following temperature transportation and storage process: between -25 and +55 ℃, in a short time (not more than 24h) up to +70 ℃, the device should not be subjected to any irreversible recovery at this extreme temperature It should be able to work normally under normal conditions.
