Description:
- Bussmann® series Indicating and non- indicating E-Rated, current-limiting, medium voltage fuses for potential, small power and control transformers.
Contents
- 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, non- venting 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. T ypical applications:
- Primary protection of:
- Medium voltage potential transformers
- Small medium voltage service transformers
- Small medium voltage control transformers. PT Medium voltage fuses for potential and small power transformers
