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. Ferraz Shawmut's line of medium-voltage UL Listed fuses fills the bill with E-rated, R-rated and capacitor fuses.
R-rated MOTOR STARTER FUSES Amp-trap R-rated fuses are current-limiting, high interrupting rating fuses intended for the short-circuit protection of medium voltage motors and motor controllers. R-rated fuses are back up fuses that have a minimum interrupting rating, and must be coordinated with overload relays in combination motor starters. The motor starter manufacturer generally specifies the R- …more
