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.
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 are also available with composite-polymer silicone insulators.
S&C’s Type XS Fuse Cutouts are manufactured in accordance with a quality system certified to ISO9001:2000.
