• Low 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-rating
• E-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 less
• PT fuses are physically dimensioned for easy installation in existing hardware
• Current limiting fuses provide positive interruption even on low fault currents
• The fuse limits the magnitude of electromechanical stresses in the protected apparatus
• These fuses are in a self-contained, non-venting package for installation indoors or outdoors in an enclosure
