• Description: Medium Voltage Fuses
• Manufacturer: LITTELFUSE [Littelfuse]

E Rated Potential Transformer Fuses
Current Limiting
Potential Transformer (PT) fuses are current limiting fuses
with high interrupting ratings designed for the protection of
potential transformers.
Application Note:
When applying fuses for the protection of transformers,
the magnetizing current inrush must be considered. The
characteristics of the inrush, which can be matched with
a fuse’s time-current curve, should be available from the
transformer manufacturer.
