All General Purpose Circuits, Motors, Transformers and Safety Upgrades Applications
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
