CNF-BMODEL
Structure is achieved by the pursuit of high capacity.Accommodates units within a height of 1,800 mm, housing up to 18 units of two sets of 100 AF / 3P MCCB.
Structure assures outstanding operability, maintenance performance, and safety.Features double-door construction (inside door, outside door), and the inside door—i.e., unit front—is fitted with a protective cover that leaves only the MCCB operating handles exposed.The transparent safety cover fitted to the MCCB power supply side ensures safe execution of maintenance/inspection work even when the inside door is left open.
Structure assures ease of installation and wiring.Constructed to the same casing depth and configured with the same busbar scheme as the Type-B Motor Control Center, this model permits contiguous installation and direct connection of busbars of both panels.With its B wiring (standard), connection to external devices is easy through the front of the panel.

The Mitsubishi Distribution Board Model CNF-B plays a key role in supplying power to and protecting permanently-installed equipment for buildings such as power and lighting facilities.
It provides the functions needed to implement power supply, overcurrent protection, short-circuit protection, and load switching for power and lighting facilities. Requiring modest installation space, the CNF-B is installed contiguously with a control center to enable efficient central monitoring. Various safety systems are duly provided. In addition, the distribution panel is designed with full consideration for ease of maintenance, inspections, and usability (ease of monitoring). CNF-B features state-of-the-art performance for switching power and lighting circuits and for switching main and standby power supplies.

Unit
The horizontal busbars are configured vertically in an upper section on the rear side, so that load cables can be led in from either top or bottom.The upper section space on the front side can be used as wireways when configuring wiring between panels: for example, for shared circuits for a control line or an interlocking circuit.Size of the neutral phase of the 3-phase, 4-line horizontal busbar is 1/2 the size of the other phases as standard.
Vertical busbar (copper, tin plated)
Horizontal busbar (copper, tin plated)
Maintenance works can be carried out from the front side such as connectin of horizontal busbars or tightening of connection bolts.
Both front and rear side of vertical busbars are covered with steel plates.

You can use the rear of the panel as a space for the incoming main circuit power supply or as a space to accommodate devices such as contactors for lighting.(The rear of the panel is used to accommodate terminals for C wiring.)A unit can be accommodated at the rear of the panel. Please contact us in advance if you need such a configuration change.(The total rated current of the units must not exceed 700 A/900 A, the capacity of the vertical busbar.)
