  • Features
  • Extremely current limiting - reduces damage to circuits and equipment under short circuit conditions
  • Stops damaging short circuits faster than any mechanical protective device
  • Reduced costs - current limiting design often permits use of readily available, less costly equipment
  • Low resistance design reduces power consumption and utility bills
  • Excellent 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 needlessly
  • Eliminates needless downtime caused by power surges or equipment demands
  • 200 kA at 250 VAC, 20 kA at 125 VDC interrupting rating
