MV fuses

 

PL, PM, PQ medium-voltage fuse-links are used for protecting the MV sides of distribution transformers and other devices working with voltage greater than 1000 V a.c. The fuse-links reliably interrupt all currents from their rated breaking capacity I1 down to the minimum breaking current I3 as specified on the fuse-links‘ label. They have a limited function range, protecting against short circuit and higher overcurrent (back-up). They are intended for both outdoor and indoor applications.
