Standardisation of the switchboard
With optimised sizes, the Masterpact NT and NW ranges simplify the
design of switchboards and standardise the installation of devices:
>
a single connection layout for Masterpact NT
>
three connection layouts for Masterpact NW:
• one from 800 to 3200 A
• one for 4000 A
• one up to 6300 A
>
horizontal or vertical rear connections can be modified on-site by
turning the connectors 90° or they can even be replaced by front
connection terminals
>
identical connection terminals for the fixed or draw-out version for each
rating (Masterpact NW)
>
front connection requires little space because the connectors not
increase the depth of the device.
Practical installation solutions
The Masterpact NW range further improves the installation solutions that have built the success of its predecessors:
>
incoming connection to top or bottom terminals
>
no safety clearance required
>
connection:
• horizontal or vertical rear connection
• front connection with minimum extra space
• mixed front and rear connections
>
115 mm pole pitch on all versions
>
no derating up to 55 °C and 4000 A.
