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.
Beyond our line of ANSI / IEEE current-limiting fuses, Mersen offers a full line of medium voltage fuse links according to the IEC standards. Among them, the back-up current-limiting fuse-links designed according to IEC 60 282-1 and meeting DIN 43 625 fuse-link dimensions. These fuse-links’ operating range is between their minimum interrupting rating (I3) and their maximum interrupting rati …more
