Characteristics of the MN5 Low Voltage Draw Dut Switchgear
Compact Design: More functional units could be accommodated in a smaller space, saving the volume of the cabinets. MCC cabinet can accommodate 36 pcs of 8E/4 drawers. The drawer unit is charaterized by its compact volume, strong function, accurate orientation and stung interchangeability, suitable for installation of third or fourth class air switch. It has reliable mechanical interlock. The effective installation height of the functional unit is 180n mm. The solid type or drawer type could be organized freely in the same switchgear.
Unified structure, flexible assembly:
The 25mm C一profile sectional materials can meet the requirements of various structural forms protection levels and operational environment.
The use of standard modular design: It can be organized into the standard units for protection operation, conversion, control, regulation, measuring and instruction. The user can make option according to the needs of any assembly. With more than 20Q assembling parts, different shelves structures and drawer units could be organized.
Safety: A large number of high一strength flame一retardant engineering plastics components are adopted, which effectively enhances the performance of the protective security.
The vertical bus channel adopts breaking functional board in wuich the right angle L type branch bus is inserted.
The MCC cabinets can be arranged back to back.
Easy assembiying: No special complicated tools are needed.

 

Conditions of Use
Indoors. Height above Sea Level ≤200 M
Ambient Temperature≥-50℃+40℃,Average Maximum daily Temperature ≤+35℃.
Relative Humidity:≤ 50% at +40℃ (Max); At a lower temperature to allow a greater relative humidity (for example 90% at +20℃)
Seismic Intensity: VIII
