Interlock Each MCC unit can be operated in three different modes: JJ Inserted/Connected (I): In this operation mode the power terminal block and the control circuit are connected to the busbar and the units are ready to run. JJ Test (T): In this operation mode the power terminal block is disconnected from the busbar, however the control circuit is energized and ready to be tested. This operation mode is useful when the control source is the same for the whole MCC. JJ E xtracted/Disconnected (E): In this operation mode the power terminal block and the control circuit are disconnected from...

4b Constructive Form Looking for enhanced security in relation to operation, maintenance and handling, WEG developed MCC-03 / MCC-03i in 4b constructive form, according to IEC60439. JJ Separation of busbars from all functional units. JJ Separation of all functional units from one another. JJ n the 4b construction, the rear access is necessary (cables connection in the rear part). I JJ ear doors are split into two, reducing the necessary access space, increasing the walkway / escape area R in case of emergency. JJ he power cables connection are placed in the same compartment (terminal block...

Intelligent MCC The intelligent MCCs are composed by motor starters (softstarters, variable frequency drives or microprocessed relays), designated as the slaves, and by a Programmable Controller installed in the same or in an adjacent MCC, designated as the master. In this architecture the PLC (master) controls and monitors all MCC devices (slaves). Information regarding MCC devices is available through local/remote Human-Machine Interfaces or PCs (supervisory system). From the HMI you can: JJ Control the motor starter. JJ Read unit status from units (Inserted/Test). JJ ead motor data,...
