The Sure Guard ETP back-up current-limiting fuses are designed to protect overhead distribution systems and are used in series with another protective device (such as an expulsion fuse). This combination limits the high-fault current to a safe level, thus providing protection through the complete range. As its name implies, the “ETP” is for External Transformer Protection. For conventional transformers protected by expulsion-fuses cutouts, the ETP can be installed in series with the cutout. For self protected transformers, the ETP can be applied on the high-voltage bushing in series with the internal transformer expulsion fuse.

Mersen USBB UltraSafe bus bar systems are intended for use with
UltraSafe Class CC (USCC) and Midget (USM) fuse holders. The USBB
delivers safe and reliable combination of circuits in a compact design. Bus
bar systems reduce installation time when compared to wire solutions,
offer space savings and deliver touch-safe, shock resistant solutions to
panel builders and designers. 1-, 2-, and 3-phase designs available.
