Features of MN5 low-voltage withdrawable switchgear
Compact design: more functional units can be accommodated in a smaller space, saving cabinet volume,
The MCC cabinet can be installed with 36 8E/4 drawers or 9 8E drawers at most. The drawer unit has the characteristics of small size, strong function, accurate orientation and strong interchangeability. It is suitable for installing three-pole or four-pole air switch and is reliable. The effective installation height of the functional unit is 1800mm, which can be freely combined into two forms of fixed type and drawer type in the same cabinet.
Strong structural versatility and flexible assembly: The C-shaped profile with 25 mm as the touch count can meet the requirements of various structural forms, protection levels and use environments
Adopting standard module design: standard units for protection, operation, conversion, control, adjustment, measurement, and indication can be formed separately, and users can choose and assemble them according to their needs. With more than 200 kinds of assembly parts
The cabinet frame structure and drawer unit of different schemes can be composed.
Safety: A large number of high-strength flame-retardant engineering plastic components are used to effectively strengthen the protection and safety performance.
The vertical bus channel adopts a split function board, and the right-angle dagger-shaped branch bus is embedded in it
MCC cabinets can be arranged back to back
Convenient assembly: no special complex tools are required.
Conditions of Use
a. For indoor installation and use, the altitude does not exceed 2000M.
b. The ambient air temperature should not exceed +40℃, not lower than -5℃, and the highest daily average temperature should not exceed +35℃.
c. Relative humidity: the highest temperature does not exceed 50% at +40℃. Relative humidity is allowed at lower temperature (for example, 90% at +20°C)
d. Seismic intensity: Grade 8.
e. The vertical inclination of the cabinet body shall not exceed 5 degrees during installation.
f. There should be no violent vibrations, shocks and insufficient corrosion of electrical components in the installation site.
g. When the user has special requirements, it can be resolved through consultation with the manufacturer.
