SM and SML Power Fuses are especially suited for protecting cables and medium-to-large power transformers on utility, as well as industrial, commercial, and institutional power systems through 34.5 kV. They incorporate precision-engineered nondamageable silver or nickel-chrome fusible elements with time-current characteristics that are precise and permanently accurate — assuring not only dependable performance, but also continued reliability of system coordination plans.

S&C’s SM and SML Power Fuses are manufactured in accordance with a quality system certified to ISO9001:2000.

SM Power Fuses are especially suited for protecting transformers, capacitor banks, and cables in outdoor distribution substations through 34.5 kV. Their precision-engineered nondamageable silver or nickel-chrome fusible elements have time-current characteristics that are precise and permanently accurate — assuring not only dependable performance, but also continued reliability of system coordination plans.

With SM Power Fuses, source-side devices may be set for faster operation than practical with other power fuses or circuit breakers, thereby providing better system protection without compromising coordination.

S&C Type XS Fuse Cutouts, when fused with S&C Positrol® Fuse Links, provide full-fault-spectrum protection for overhead distribution systems rated 4.16 kV through 25 kV, whether applied on overhead transformers, capacitors, cables or lines.

This performance also extends to solidly grounded systems rated 26.4 kV through 34.5 kV, for protection of single-phase-to-neutral lines and transformers and grounded-wye-connected capacitor banks. “Full-fault-spectrum protection” means that Type XS Fuse Cutouts will interrupt all faults — from the lowest current that will melt the fuse link to the maximum rated interrupting current — under all realistic transient-recovery-voltage conditions.

S&C’s Type XS Fuse Cutouts are manufactured in accordance with a quality system certified to ISO9001:2000.

S&C’s SMD Power Fuses provide reliable, economical protection for transformers and capacitor banks in outdoor substations through 138 kV. They incorporate precision-engineered non damageable silver or nickel-chrome fusible elements with time-current characteristics that are precise and permanently accurate — assuring not only dependable performance, but also continued reliability of system coordination plans.

The Loadbuster tool is the original lightweight, easy-to-use portable loadbreak tool for use with disconnects, cutouts, power fuses, and fuse limiters. It brings load-switching capability through 34.5 kV and 600 amperes nominal, 900 amperes maximum to your overhead distribution system.

The Loadbuster tool cuts installation and operation costs. There’s no need for load interrupters on each device. Switching procedures are simplified too . . . minimizing the duration and scope of outages. This rugged, reliable device interrupts with no external arc, meeting OSHA requirements for opening circuits under load.

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.
