Potential Transformer fuses

PT series fuses are current limiting, non-indicating, partial range HRC fuses available in a variety of voltage, amperage and interrupting ratings. (see chart).

FC series are North American dimensioned PT fuses and provide equals to Westinghouse and CGE.  BPT series are British dimensioned PT fuses and offer equals to GEC, Brush, CCL, and EMP.

-    Pure silver elements
-    Fully plated metal parts for cool running.
-   Excellent current limitation for substantial reduction of short circuit stresses.

   

Retrofitting

Fusetek PT fuses can replace any other manufacturers' PT fuse with same dimensions and voltage/amp rating. When replacing fuses, ensure that fuse clips still have good spring tension. Adjust or replace if necessary. Make sure contact surfaces are clean and free of corrosion
