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 in-rush must be considered. The characteristics of the in-rush,
which can be matched with a fuse time-current curve, should be
available from the transformer manufacturer.
