Your Problem: On one hand, you need current-limiting protection for medium voltage transformers and distribution systems. On the other, you need short circuit protection for your plant's medium voltage motors and motor controllers. In both cases, you want a range of configurations to simplify changeouts. Reduced clearances to optimize cabinet space. And the confidence of UL.

Our Solution: Welcome to the Ferraz Shawmut Amp-trap^®medium voltage UL fuse line. Our E-Rated models for transformers and distribution systems are UL listed. They're available in 5.5kV, 10E to 900E and 15.5kV, 10E to 300E ratings, And they come in three configurations. Additionally, our R-Rated models (rated for 4800, 2R to 36R and 7200V, 2R to 24R) are UL Recognized - and provide reliable short circuit protection for MV motor controllers and motors.
