POWR-GARD^® Fuse Datasheet
E-RATED POTENTIAL TRANSFORMER FUSES
Description
Potential Transformer (PT) fuses are current-limiting fuses
with high interrupting ratings designed for the protection of
potential transformers.
Characteristics
Voltage Ratings 625 Vac – 25,800 Vac
Current Range 1/2E – 10E
Application Note
Dimensions
When applying fuses for the protection of transformers,
the magnetizing current in-rush must be considered. The
characteristics of the in-rush, which can be matched with
B
a fuse time-current curve, should be available from the
­transformer manufacturer.
