The MDmax-ST low-voltage switchgear adopts a modular structure in its structural design, by selecting standard components and standard groups To achieve compactness, diversity, and flexibility in cabinet assembly solutions. Different types of switchgear can be combined according to requirements, such as fixed type, fixed partition type, and drawer type. In terms of functionality, power distribution, reactive power compensation, motor control center (MCC), AC frequency converter, soft start device, etc. have been considered. The MDmax-ST low-voltage switchgear has the characteristics of multifunctionality and modularity, making it suitable for low-voltage distribution in various occasions, as well as motor control systems in enterprises such as metallurgy, chemical, and power plants.
