General info
MNS Low-voltage combination switchgear is assembled with modules in the factory and is used in the powering system of AC 50-60Hz and rated working voltage under 660V. It meets the relative technical requirement of international standard IEC439, national standard GB7251 and major standard ZBK36001.
It is suitable for all power distribution systems and locations that require a three-phase alternative current with a frequency of 50(60)Hz and a rated voltage from 380V to 660V such as power systems, petrochemical industries, public utilities, residential areas, drilling platform, mining enterprises, etc.
Parameters
Rated voltage 380V
Rated power current 100~4000A
Rated short time withstand current 65kA
Rated peak withstand current 136kA
Drawing
Standard Characteristics:
1. Compact design:
2. High commonality of the structure and flexibility of assembling. The cubicle body is made up of C-type material with modulus 25mm, it meets the requirements of different structural types, protection categories and operation environment.
3. Modular design: different modular units form standard units of protection, operation, transformation, control, regulation, measurement or indication. Users can freely choose them to assemble what they want. More than 200 assembly components can form different projects of frame configurations and drawer units.
4. Safety: using lots of plastic components of high strength preventing-burning to increase safety.
5. High technology: main parameters reach international technology level.
6. Smaller space: Higher level of miniaturization, smaller space to store and transport pre-manufactured components.
7. Easy to be assembled, no need of special complicated tools.
Details
Service conditions
◎ Ambient airtemperature should be within -5°C~+40°C, average temperature within 24h should not exceed +35°C.
◎ Atmospheric conditions: air should be clean. Relative humidity should not exceed 50% at +40°C, higher relative humidity is allowed at lower temperature condition, for instance, 90% at +20°C, please take measures for the dew produced on the product caused by temperature change occasionally.
◎ Altitude: not exceed 2000m.
◎ Ambient temperature for storage and transportation: -25°C~+55°C, short time (usually not beyond 24h) highest temperature not exceed 70°C. The product should not be subject to any irreversible damage underthe extreme temperature and should be able to work normally underthe normal conditions.
