Optimised volumes and ease
of installation
Aiming at standardising electrical switchboards at a time when
installations are increasingly complex, Masterpact provides an
unequalled simplicity, both concerning choice and installation.
The smallest circuit breaker
in the world
Masterpact NT innovates by offering all the
performance of a power circuit breaker in an
extremely small volume. The 70 mm pole pitch
means a three-pole draw out circuit breaker can
be installed in a switchboard section 400 mm
wide and 400 mm deep.
Maximum security
The arc chutes absorb the energy released
during breaking, thus limiting the stresses
exerted on the installation.
They filter and cool the gases produced,
reducing effects perceptible from the outside.
Optimised volumes
Up to 4000 A, Masterpact NW circuit breakers
are all the same size, the same as the old M08
to 32 range.
From 4000 A to 6300 A, there is just one size.
More than
60
patents are used to
design Masterpact
Retrofit solutions
>
Special connections terminals are available to replace a fixed or a drawout Masterpact M08 to 32 with a Masterpact NW,
without modifying the busbars or the door cut-out.
>
"Plug and Play" retrofit solution : this solution enables retrofitting of Masterpact M units with considerably reducing on-site
intervention time and getting the performance of last generation device.
The original Masterpact M chassis is kept (no
intervention on the switchboard structure)
