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.

All Type XS Fuse Cutouts employ an S&C-developed innovation — single venting, down and away only — an especially important feature where exhaust must be kept out of other phases in overbuilt circuits. There are no costly-to-replace expendable fuse-tube caps.

Type XS Fuse Cutouts provide superior mechanical handling and electrical performance, including:

  • Easy fuse link installation — even with gloved hands
  • Easy fuse tube insertion (and removal)
  • Superb alignment when closing — from any angle and under adverse conditions of light and weather
  • No fuse link breakage
  • Completely reliable dropout action — regardless of fault-current level
  • Mates perfectly with S&C’s Loadbuster® Tool — for sure, reliable load switching

Single-Shot Overhead — Pole-Top Style Type XS Fuse Cutouts are sold in the U.S. and Canada by MacLean Power Systems. For additional information, please visit their website at www.macleanpower.com.

Operation with Loadbuster, S&C’s Portable Loadbreak Tool:

Attach.

Reach across the front of the cutout and attach Loadbuster’s anchor to the attachment hook on the far side of the cutout, and then engage its pull ring with Loadbuster’s pull-ring hook. Loadbuster’s pull-ring latch prevents inadvertent disengagement of the cutout pull ring and Loadbuster’s pull-ring hook.


Pull.

A firm, steady downward pull on Loadbuster — to its maximum extended length — opens the cutout in the normal manner as the current is diverted through Loadbuster. At a predetermined point in the opening stroke, Loadbuster trips, breaking the circuit positively.


Remove.

Loadbuster is disengaged by first removing its anchor from the cutout attachment hook. Then, with the blade in the open position, Loadbuster is removed from the pull ring with a simple “roll-off” motion.

The Coordinaide protection and coordination assistant software lets you quickly and easily select the optimal protective device (e.g., fuses, TripSaver II Cutout-Mounted Reclosers, Vista® Underground Distribution Switchgear, or IntelliRupter® PulseCloser® Fault Interrupters) to:

  • Protect transformers against damaging overcurrents and coordinate with primary- and secondary-side protective devices.  See how S&C's novel Transformer Protection Index (TPI) can be used to determine if the primary fuse will protect against certain types of secondary-side faults, including arcing phase-to-ground secondary-side faults.
  • Protect capacitor units against case rupture.
  • Protect underground cables from insulation damage due to excessive temperatures.
  • Protect overhead conductors from damage due to annealing.
  • Confirm the proper operation of protective devices against incident-arc energy curves for various Personal Protective Equipment (PPE) levels.
  • Selectively coordinate two or more devices in series to minimize service interruptions.
