The primary purpose of any drop-out fuse cutout is to provide protection of the lines of your system and the various apparatus on those lines such as transformers and capacitor banks. Our cutouts provide reliable protection from low-level overloads, which just melt the fuse link, intermediate faults, and very high faults— through maximum interrupt capacity. Moreover, these types of cutouts can be sectionalized. A portable load break tool can be employed, and it acts as an overhead disconnect switch. There is also a 300-amp disconnect blade available for this purpose. Interrupting tests have been performed at full system line-to-line voltage. Continuous current ratings exist at each voltage level in the 100-amp, 200-amp, and 300-amp classes.
