Compact Design: more functions, small space
MCC cabinet can accommodate 36 pcs of 8E/4 drawers or 9 pcs 8E drawers. The drawer unit is compact volume, strong function, accurated orientation and exchangable, which is suitable for installation of third or fourth air protection switchgear. It has reliable mechanical interlock with the effective installation height by 1800 mm. The installation can be solid type or drawer type in one switchgear.
Common structure, flexible assembly
The 25mm C-profile steel profile and can meet the requirements of various structural forms, protection levels and operational environment.
It can be organized into the standard units for protection, operation, conversion, control, regulation, measuring and instruction. The user can make different shelves structures and drawer units according to the needs of any assembly which has 200 types.
More high-strength flame-retardant engineering plastics components are adopted, which effectively enhances the performance of the protective security.
The vertical bus bar channel adopts breaking functional board and the right angle L type branch bus is inserted.
The MCC cabinets are installed back to back.
Easy installation: No special tools are needed.
