Fault Tamer® Fuse Limiter

For outdoor distribution, 15 kV through 25 kV

Combines the functionality of a conventional fuse cutout and a backup current-limiting fuse in one powerful, easy-to-install package

S&C Fault Tamer combines the functionality of a conventional fuse cutout and a backup current-limiting fuse in one powerful, easy-to-install package for the protection of new or existing overhead pole-top transformers through 25 kV. Fault Tamer addresses the critical issues facing protection engineers today.

Fault Tamer is manufactured in accordance with a quality system certified to ISO9001:2000.

Features:
Fault Tamer provides these features and benefits over traditional fuse cutouts, or cutouts used in combination with backup current-limiting fuses.

Improved Transformer Protection
- Ideally suited for protecting single- or three-phase transformers through
100 kVA single-phase at 15 kV
167 kVA single-phase at 25 kV
- Excellent continuous, hot-load pickup, and cold-load pickup capabilities.
- High surge withstand capability. Allows arrester to be mounted on transformer tank without increasing the chance of nuisance operations due to lightning.

Energy Limitation
- Minimizes equipment damage
Reduces chances of catastrophic transformer failure from internal high-current faults.
Minimizes bushing and tank damage due to external primary faults.
- Improves service continuity
Provides complete coordination with upstream lateral fuses.
Provides complete coordination with substation instantaneous relay settings.
- Enhances power quality
Minimizes voltage dips that can cause sensitive electronic equipment to shut down.
