On one hand, you need current-limiting protection for medium-voltage transformers and distribution systems. On the other, you need short circuit protection for medium-voltage motors and motor controllers. Mersen's line of medium-voltage UL Listed fuses fills the bill with E-rated, R-rated and capacitor fuses.
2.75kV FERRULE MOUNTED FUSES 9F60 series fuses have 2 or 3 Inch diameter barrels with ferrules and are mounted in spring reinforced clips. Some are outdoors rated. The unique time-current characteristic of Mersen E-Rated fuses allows them to be closely sized to transformer full-load rated current, as recommended by IEEE guidelines, without being affected by normal magnetizing inrush cu …more
