PT Fuses

2.475kV to 38kV PT medium voltage fuses

For potential and small power transformers

General purpose, low amp, current-limiting E-Rated PT medium voltage fuses are defined by their melting time-current characteristic that permit their electrical interchangeability with other fuses of the same E Rating.

Physically dimensioned for easy installation in existing hardware and provide designers a space saving size for new installations.

Self-contained in a non-venting package, PT fuses may be installed indoors or outdoors in an enclosure.

Available in non-indicating versions and indicating versions for faster troubleshooting with a positive visual indication of fuse operation.

Typical applications:

  • Medium voltage potential transformers
  • Small medium voltage service transformers
  • Small medium voltage control transformers
