3 Functions and characteristicsGeneral characteristicsCompliance with standardsE28472 Compliance with North American standardsCOMPACT NS circuit breakers are built in accordance with UnderwritersLaboratories Inc. UL 489 Standard and Canadian Standards Association CSA Standard. Circuit breakers, switches and their accessories, except wherenoted, are Listed under UL files E63335, E103740, E103955, and Certified underCSA files LR69561 and with international standardsCOMPACT NS circuit breakers and their accessories comply also with the followinginternational standards:nIEC 947-1: general rules;nIEC 947-2: circuit breakers.

4 NIEC 947-3: switches, disconnectors, switch disconnectors, that these standards are applied in most countries, COMPACT circuit breakersand their accessories comply with European (EN 60947-1 and EN 60947-2) and thecorresponding national standards:nFrance NF;nGermany VDE; BS;nAustralia AS;nItaly with the specifications of marineclassification organizationsCOMPACT NS circuit breakers have been approved for marine application by theAmerican Bureau of Shipping, Bureau Veritas, Lloyd s Register of Shipping, RegistroItaliano Navale, Germanischer Lloyd s and Det Norske comply with the following standards:nUL 489 Supplement SA.

5 Marine use on vessels over 65 feet in length;nUS Coast Guard specifications;nIEC 92-504 and marine specifications: inclination, vibrations, insulation resistance;nIEC 803 Electromagnetic Disturbance NS circuit breakers comply with NF C 63-100 standard level 2conditions (95% relative humidity at 45 C or 80% at 55 C, hot and humid climateconditions).They also comply with the following standards:nIEC 68-2-30 damp heat;nIEC 68-2-2 dry heat;nIEC 68-2-11 salt spray;nIEC 68-2-1 low degreeCOMPACT NS circuit breakers are certified for operation in pollution degree IIIenvironments as defined by IEC standard 947 (industrial environments).

6 Environmental protectionCOMPACT NS circuit breakers take into account concerns for environmentalprotection.

7 NPadlocks may not be installed unless the contacts are of a rotary handle or a motor mechanism does not alter the functionalityof the position indication isolation function is certified by tests guaranteeing:nThe mechanical reliability of the position indication system;nThe absence of leakage currents;nOvervoltage withstand capacity between upstream and downstream for isolation (positive contact indication)Installation in Class II switchboardsAll COMPACT NS circuit breakers, even when fitted with a rotary handle or a motormechanism, can be installed through the door of Class II IEC switchboards (as perIEC 664 Standard).

8 Refer to circuit breaker installation instructions prior to installingcircuit requires no special insulation because COMPACT NS circuit breakersprovide Class II insulation between the front face and all internal markingCOMPACT NS circuit breaker: functions and characteristicsCircuit breaker marking5 COMPACT NS circuit breakerCircuit breaker current limiting capacityThe limiting capacity of a circuit breaker is its ability tolimit short-circuit current limiting capacityThe exceptional limiting capacity of the COMPACT NS line is due to the doublebreak technique (very rapid natural repulsion of contacts and the appearance of twoarc voltages in series with a very steep wavefront).

9 The exceptional limiting capacity of the COMPACT NS line greatly reduces theforces created by fault currents in devices. The result is a major increase in breakingperformance. In particular, the service breaking capacity Ics is equal to 100% of Ics value, defined by IEC 947-2, is guaranteed by tests comprising the followingoperations:nBreaking a fault current equal to 100% of Icu three times consecutively;nChecking that the device continues to function normally:qConduction of rated current without abnormal temperature rise,qProtection functions perform within the limits specified by the standard,qSuitability for isolation is not service life of electrical installationsE28801 Current limiting circuit breakers greatly reduce the negative effects of short circuitson effectsLess temperature rise in conductors, therefore longer service life for effectsReduced electrodynamic forces.
