General
MNS low-voltage withdrawable switchgear is a new product developed
recently. Its technical level has reached the international
advanced level of this century. This product has a compact design,
strong structure versatility, flexible assembly, and standard
modular design. It is a safe, economic, reasonable and reliable new
low-voltage withdrawable switchgear. The product has the
characteristics of high breaking capacity, good dynamic and thermal
stability, flexible electrical scheme and high protection level.
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.

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 do 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.
