Extremely current limiting - reduces damage to circuits and equipment under short circuit conditionsStops damaging short circuits faster than any mechanical protective deviceReduced costs - current limiting design often permits use of readily available, less costly equipmentLow resistance design reduces power consumption and utility billsExcellent time delay - true dual element construction, with separate non-fatiguing thermally-reversible spring loaded thermal overload element, withstands repeated surges within rated time delay without opening needlesslyEliminates needless downtime caused by power surges or equipment demands200 kA at 600 VAC, 20 kA at 300 VDC interrupting rating
