  Catalogue2008 Low Voltage Compact NS Circuit breakers and switch-disconnectors from 80 to 3200 A  Compact NS, setting the standard, once again... The launch of Merlin Gerin Compact NS in 1994 revolutionised the world of moulded-case circuit breakers. Innovative, exible and attractive, Compact NS rapidly set the standard in its eld. Today, Schneider Electric continues to innovate, extending the Compact NS range to high power ratings to offer a comprehensive and consistent range from 80 to 3200 A.Equipped with the new generation of Micrologic control units, Compact NS630b to 1600 circuit breakers now offer built-in power and energy    metering in addition to electrical measurement and analysis functions.The communications option makes it possible to control power consumption, simplify maintenance and improve operating comfort. A wide range of optimised auxiliaries  and accessories is also available to meet the needs of even more applications. Compact NS, simply a step ahead…       0      4      6      7      5      1   -      1      3 Compact NS80A.       P      B      1      0      1      0      4      5   -      1      5 Compact NS100 to 250 A.       P      B      1      0      1      0      4      4   -      1      9 Compact NS400 to 630 A.       D      B      1      1      2      5      2      9 Compact NS630 to 1600 A.       E      4      5      1      7      8      R   -      6      0 Compact NS1600 to 3200 A.  Compact NS General contents Introduction3Functions and characteristicsA-1Installation recommendationsB-1Dimensions and connectionC-1Wiring diagramsD-1Additional characteristicsE-1Catalogue numbers and order formsF-1 1  2 Additional earth-leakage protection protects life and property against the risks of faulty insulation in the installation. Depending on the circuit breaker, earth-leakage protection is provided by:adding a Vigi module to the circuit breaker  using a specic Micrologic control unit using a Vigirex relay and separate toroids. bbb Compact NS, even more applications... Protection for:distribution systems supplied by transformersdistribution systems supplied by engine generator setslong cables in IT and TN systems.Installation : in power switchboardson DIN rails (see page A-36)Special applications: single-phase and two-phase systems (see page A-22)1000 V distribution systems (see page A-28)400 Hz distribution systems (see page A-26)DC systems (see page A-32). All circuit breakers in the Compact NS range offer positive contact indication and are suitable for isolation in compliance with standards IEC 60947-1 and 2. bbbbbbbbb Protection of LV distribution systems page A-4 When combined with a motor starter, Compact NS circuit breakers protect the cables and the starter against short-circuits. Equipped with an electronic trip unit, Compact NS circuit breakers also protect the cables, starter and motor against overloads.The exceptional current-limiting capacity of Compact NS circuit breakers automatically ensures type-2 coordination with the motor starter, in compliance with standard IEC 60947-4-1.The different circuit-breaker versions in the Compact NS range are designed to meet the specic requirements of machines: compliance with international standards IEC 60947-2 and UL 508 / CSA 22-2 No. 14compliance with U.S. standard UL 489protection against overloads and short-circuits positive contact indicationinstallation in universal and functional enclosures. bbbbb    E   2   0   9   9   9 Protection of motor feeders page A-42Protection of machines page A-50    E   4   4   3   5   6 Earth-leakage protection page A-54    E   4   4   3   5   7   E   2   6   9   8   8
