Distribution Transformer Protection

Sure Guard 9F59U Series ETP Fuses

8.3kV / 15.5kV / 23.0kV ETP fuses

The Sure Guard ETP back-up current-limiting fuses are designed to protect

distribution transformers 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.

Features/Benefits:

•

Various hardware options.

•

Current-limiting for superior equipment protection.

•

High fault current interrupting capability: I.R. Sym = 50kA at ETP voltage rating.

Highlights:

•

Outdoor use

Applications:

•

Overhead distribution systems

Definitions:

Back-up Current-Limiting Fuses:

A back-up current-limiting fuse is a fuse that can interrupt any current between its rated

minimum interrupting current and its maximum interrupting current. Back-up fuses are

not designed or intended to open under overload conditions.
