Your installations evolve,our solutions tooIn a constantly changing industrial and economic world,

you need to be able to upgrade your installations at all

times to remain competitive.

Only electrical installations made up of modular

switchboards are able to meet the challenges you face.

with normabloc, you are completely free to add new

feeders to your motors.

Simply modular and open-

endedThe modularity of the normabloc functional

switchboards means.

you can modify or upgrade them with ease to adapt to

your changing processes and thus increase

performance. The withdrawable drawers let you make

these upgrades while the equipment is energised,

without cutting switchboard supply and in a completely

safe environment.

The switchboard is designed with free slots to add

new functions or extra motor feeders, even at the last

minute.

Connection

High electrodynamic withstand capacity and

suppression of the arc tracking risk.Supplying bars immerse inside a cast block of resin

and silica.

Fully withdrawable equipment.Equipments isolation and unlocking are obtained by a

removable crank handle for circuit breakers on cradle,

and by a handle for drawer type equipments.

Easy transformation for drawer - type

equipments. Change of module by simple removing of

slides and partition plates, the switchboards remaining

alive.

Maximum installation facility.Large rear volume for cables connection.

Distribution and motor control centerModular design withdrawable equipments up to 6000

Amps.

The N 660 low voltage switchboards answer all the

needs of repartition and distribution of energy set in large

industries. Equipments enable them to be adapted to the

most various installations complying in the same time

with the most strict way to the following requirements:

operation facilities

personal safety

flexible design

reduced dimension

most of the protection function, circuit-breaker or

contactor, are withdrawable, therefore easy to

disconnect and to interchange. The relaying or interlock

and control devices are regrouped on a fixed or draw-out

type independent panel, enabling, without breaking the

power circuits, a possible control or intervention.

The N680 series receive " cradle-type" equipment (Air circuit-breakers rated currents 2500Amps and (moulded case circuit-breakers rated current<1250 Amps) and drawer type equipment (moulded case circuit-breakers rated current < 630 Amps,contactors rated current < 500 Amps ) for the realization of distribution or motor control switchboards.

They form a range of cubicles with the following

standardized dimensions:

- height 2350 mm

-depth :600 mm

Width is determined according to the dimensions of

the biggest equipment inside the cubicles and

according to the type and section of cables.

Frames are made up of folded sheet steel elements

bolted together,and have at their lower part a base

ensuring rigidity and avoiding thus any adjustments

during installation. They are covered with heat treated

epoxy powder paint.
