Fault Tamer^® Fuse Limiters

Introduction

Fault Tamer Fuse Limiters combine the functions of a conventional fuse cutout and a backup current-limiting fuse in one powerful package which can be easily incorporated in new or existing installations of 14.4-kV, 25-kV, and 34.5-kV overhead pole-top transformers. Fault Tamer addresses the critical issues facing protection engineers today.

• Current-limitation — Fault Tamer protects against high-magnitude internal faults and bushing flash-overs.
• Improved service continuity — Fault Tamer coordinates with lateral fuses over the full range of faults, coordinates with station breaker’s instantaneous setting . . . eliminates momentary interruptions.
• Enhanced power quality — Fault Tamer reduces voltage dips . . . faults won’t affect sensitive electronics served by adjacent feeders.
• Maximum surge protection — high inrush withstand allows tank mounting of arresters . . . without nuisance fuse operations.
• Simpler handling — since Fault Tamer’s combination fuse tube and limiter drop open after an operation, it can be removed from the ground using an “extendo” stick.
• Retrofittability — Fault Tamer is designed to fit into all vintages of S&C cutouts. You can upgrade to Fault Tamer’s superior current-limiting protection at minimal cost.
• Heightened safety — no parts expelled, no sparks produced.

S&C’s Fault Tamer Fuse Limiters are manufactured in accordance with a quality system certified to ISO9001:2000.
