Short Description
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
- IEC Type 2 "No Damage" protection to IEC and NEMA type motor starters
- Indicating and DIN mount fuse holders available
- POWR-PRO performance
- 200 kA RMS symmetrical at 250 VAC/20 kA at 125 VDC
