Technical Data 6002 Effective March 2016 Supersedes December 2015 BUSSMANN SERIES PT Medium voltage fuses for potential and small power transformers Features and benefits Description: • Bussmann® series Indicating and nonindicating E-Rated, current-limiting, medium voltage fuses for potential, small power and control transformers. Contents Description • 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 seconds at an RMS current within the range of 200% to 240% of the fuse’s 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. • Space saving size eases design considerations for new installations. • 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, nonventing package for installation indoors or outdoors in an enclosure. • Available in indicating and non-indicating versions. • Open fuse indicator speeds troubleshooting by providing a positive visual indication of fuse operation.
