FeaturesLow amp, current limiting e-rated PT medium voltage fuses are general purpose fuses defined by their melting time current characteristic that permit their electrical interchangeability with other fuses of the same E-ratingE-rated general purpose fuses must have a current responsive element that will melt in 300 sec at an rms current within the range of 200% to 240% of the fuses nameplate current rating, fuse refill or link per ANSI C37.46 for fuses rated 100E or lessPT fuses are physically dimensioned for easy installation in existing hardwareCurrent limiting fuses provide positive interruption even on low fault currentsThe fuse limits the magnitude of electromechanical stresses in the protected apparatusThese fuses are in a self-contained, non-venting package for installation indoors or outdoors in an enclosure
