CUBIC modular system
for low voltage switchboards LV

Modular system, free assembly
of any type of electrical switchboard

Modular low voltage (LV) switchboards up to 6300A with any electrical equipment (including Schneider Electric, Siemens, ABB). CUBIC offers solutions based on a modular system for main and distribution switchboards, MCC (drive control), control and in the 19″ rack standard. Modular solutions are available: Multi Drawer, Plug-in, MPI inserts and Cu-mini.

Multi Drawer cassette switchboards are widely used worldwide for the distribution of electrical energy while maintaining the highest possible level of safety for personnel and equipment. The Multi Drawer system is used for the distribution of electrical energy in industrial processes, mining, navigation, hospitals, infrastructure and wherever even a short interruption in the power supply can threaten human life or cause huge process disruptions and economic losses.

Torqued, two-bolt fastening system
for bus connections reduces
maintenance and exposure
it's hazardous power.

Solid top and bottom unit support pans
isolate units to help prevent a single
fault from cascading throughout
the enclosure and limit equipment
damage.

Test the control and networked circuits
without power connections.

Interlock mechanism helps prevent units
from being withdrawn or inserted when
the disconnect handle is on.

Automatic shutters isolate the vertical
bus when the unit is removed.

Form 4B separation isolates dangerous
load connections while maintenance
is performed.
