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.
CHARACTERISTICS
Voltage Rating: 600VAC – 25,500 VAC
Current Range: 1/2E – 10E
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.
