1 Merlin GerinMulti 9 SystemProtectionMiniature Circuit BreakersGet more with the world s Power & Control specialistProtectionCircuit Breaker Limitation CapabilityThe limitation capability of a Circuit breaker is that characteristic wherebyonly a current less than the prospective fault current is allowed to flow undershort- Circuit is illustrated by limitation curves which give:"The limited peak current in relation to theRMS value of the prospective short-circuitcurrent (the short- Circuit current being thatcurrent which would flow continuously in theabsence of Protection equipment)."The limited current stress in relation to theRMS value of the prospective short-circuitcurrent."Current limiting capability. The advanceddesign of the Multi-9 range provides currentlimitation with far better Protection than con-ventional Circuit breakers. For example, on a6A rating with a prospective short Circuit of5000A, the current will be limited at 350A or7%.

2 Installation of current limiting Circuit breakersoffers several advantages:#Better network protectionCurrent limiting Circuit breakers considerablyreduce the undesirable effects of short-circuitcurrents in an installation.#Reduced thermal effectsCable heating is reduced, hence longer cablelife.#Reduced mechanical effectsElectrodynamic forces reduced, thus electri-cal contacts are less likely to be deformed orbroken.#Reduced electromagnetic effectsMeasuring equipment situated near an elec-trical Circuit less Unit VariationsCircuit Breaker MarkingCurve B tripping:3 to 5 times the ratedcurrent (In); Protection of generators,persons, very Ctripping:5 to 10 In; Protection of circuits,general Dtripping:10 to 14 In; Protection of high surgecircuits, welders, trans-formers, MA(magnetic only)tripping: 12 In; Protection of motorstarters (+ thermal pro-tection when combinedwith contactor).
