An answer for
each type of
solutions:
Compact NS range…
More than 10 years of techniques and technologies.
Inventor of the unique system-block concept, Schneider Electric proposes a range of circuit-breakers to meet the concerns
of panel builders and contractors. The result of 30 years of experience in the field of electrical distribution, the Compact NS
range is still today the international reference on the moulded case circuit-breaker market.
Consistency
The Compact NS
range is available
in 4 sizes only in
order to homogenise
installation dimensions,
thus reducing
switchboard dimensions
and facilitating their
installation: volume,
depth, pole pitch and
fastening points are
the same for each size.
Efficiency
The Compact NS
technology satisfies
all your needs from 16 to
3200 A, with a breaking
capacity from 36 to
200 kA. Equipped with
electronic control units,
the Compact NS
circuit-breakers
guarantee protection
and measurement
of your electrical
installation.
Flexibility
Compact NS adapts
to all your applications:
protection of DC and
AC installations,
generator protection,
motor protection,
applications in 1000 V,
switch-disconnectors,
source changeover
switches.
With Compact NS
you have the choice.
Openendedness
Compact NS
evolves together
with your installation:
interchangeable trip
units, standardised
accessories, changing
of rating without
disassembling the device
and addition of indication
and control functions
make Compact NS the
most flexible solution
on the market.

Total control of discrimination
for optimum continuity of supply
The result of a technology that has since inspired all major manufacturers, Compact NS offers
an unparalleled discrimination level on the electrical distribution market. Fully incorporated in product
design, discrimination is available as standard on all the range devices, without addition of any extra
accessories. Should a fault occur, only the circuit-breaker placed immediately upstream from
the fault trips. Continuity of supply is thus guaranteed for the other feeders.
A comprehensive range of trip units and control units
to combine measurement and protection
The trip unit becomes a genuine control unit for the Compact NS circuit-breaker. It combines various
types of measurement with various types of protection. It measures accurately network parameters,
immediately calculates values, memorises, logs, reports, communicates, acts, etc. It is both an
extremely reliable protection device and an accurate measuring instrument. With the Micrologic P,
power measurement and advanced protection functions are now available in the Compact NS range.

Reflex tripping and exceptional current limiting
to reduce installation stresses
Thanks to reflex tripping and to the current limiting capacity of the Compact NS range,
the energy developed by the short-circuit current is limited to very low values.
The stresses undergone by the entire electrical installation located downstream
are thus greatly reduced.

Complete cascading between the products from the range
for installation savings
The high short-circuit current limiting capacity of the Compact NS range enhances the breaking
capacity of the circuit-breakers located downstream. The upstream circuit-breaker protects all
the circuit-breakers placed downstream. This greatly reduces the electrical switchboard design
cost thanks to switchgear savings.

Highly immune protection system insensitive to disturbances
for more reliable operation
Insensitive to external disturbances, the Compact NS range complies with the strictest requirements
defined by standard IEC 60947-2 (Appendix F). Devices are able to operate in their electromagnetic
environment without generating disturbances that could result in loss of quality, create a malfunction
or a failure in the electrical installation.
