Low Voltage Switchboard and Motor Control Center

M&I Modular C Series

M&I Modular C Switchboad and Motor Control Center are based on Cubic system. They are all tested and type approved by several of the most recognized test laboratories, including KEMA, ASTA, UL, DNV, Russian Maritime Register of Shipping and Germanischer Lloyd. With these certifications. M&I Modular C switchboard is perfect for generator switchboard, main switchboard and distribution boards as well as motor control center in offshore and industrial application.

M&I Modular C Low Voltage Switchboard and Motor Control Centers are of modular construction providing a high degree of versatility that allow the possibility of modifying and extending the switchboard. The modular system is used for the construction of Main switchboards, Motor Control and Starter panels, Marine Panels, Distribution boards, Draw-out panels, Plug-in panels and Control Panels. Busbar system is type-tested up to 7000A with a short circuit level of 100kA. Switchboard and Motor Control Center can be constructed with internal segregation from FORM 1 to FORM 4, ensuring optimum personal safety and operation dependability according to IEC61439-1.

M&I Modular C Switchboad and Motor Control Center panels give the greatest possible extent of freedom and  free choice of electrical components. It provides the advantage that it is only necessary to switch off one motor unit for service and maintenance, without shutting down the entire MCC panels.

In addition, our products are of high quality control and it is a complete low voltage switchboard with many possible solutions to suit customer requirements.
