1E11PT15.5 (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.
Live Parts:Live parts are available for mounting potential transformer single, double, and triple barrel fuses. Note, all clips are sold in pairs.
