FeaturesExtremely current limiting - stops damaging short circuit current faster than any mechanical protective deviceFast-acting - provides fast-acting protection to equipment such as variable speed drives, rectifiers and other equipment containing surge-sensitive componentsReliable interruption of all over currents up to 200000 ALonger equipment life - current limiting design reduces damage to equipment caused by heating and magnetic effects of short circuit currentsOften permits use of readily available, less costly equipmentNorth American style200 kA at 600 VAC, 20 kA at 300 VDC interrupting rating
