Fixed Structure Switchboard
SMB Electric Modular Switchboard is a general purpose floor standing fixed type switchgear assembly designed for use in the generation, distribution and application of electricity. The system is applicable for both Power Control Centres - Main Distribution Board and Motor Control Centres.
The construction of the System is based on precisely divided grid of 140mm in all three dimensions, thus providing maximum flexibility for the arrangement of switchgear components. The result is a systematic grouping of function-related assemblies thus providing service continuity, ease of manufacture and possibility of future system expansion
