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.

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.
