Special Features

  • British Standard VT fuses with low current ratings for use in voltage transformers or operating transformers to provide isolation of the associated system in the event of faults in the transformer circuit
  • Current limiting fuses provide positive interruption even on low fault currents
  • 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
  • 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
  • Physically dimensioned for retrofitting in existing hardware
  • PT fuses are physically dimensioned for easy installation in existing hardware
  • Space saving size
  • 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
