Potential Transformer Series – Medium Voltage Fuses
Potential Transformer (PT) fuses are current limiting fuses with high interrupting ratings designed for the protection of potential transformers.
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.
Live parts are available for mounting potential transformer single, double, and triple barrel fuses. Note, all clips are sold in pairs.
