1 Cutouts Catalog Cutouts Catalog MPS Type XS Fuse Cutouts provide full fault spectrum protection to overhead distribution systems. Whether your application is overhead transformers, capacitors, cables, or lines, our product covers systems rated 4.16 kv through 25 kv. Full fault spectrum protection means that Type XS Cutouts interrupt all faults from the lowest current melting the fuse link, to the maximum rated interrupting current. MPS cutouts protect against a fault on the transformer primary or secondary with line to line or line to ground voltage across the cutout, regardless of the transformers winding connections, and with the capability of handling a full range of transient recovery voltage severity associated with these conditions. All MPS Type XS Cutouts employ single venting down and away design. This is an especially important feature which allows exhaust to be kept out of other phases in overbuilt circuits. The nonexpendable fuse-tube cap construction eliminates the extra expense of replacement. Type XC Fuse Cutouts outdoor distrubution 4.16 kv through 25 kv Type XS Cutouts have been expressly designed for superior mechanical performance. Fusing is simple, even with gloved hands. The fuse tubes are simply inserted into the cutout hinge and easily closed without any need for careful aligning by the operating personnel. This makes installation simple even under extreme angles or adverse weather conditions. Type XS Cutouts can be opened and fuse tubes removed with equal ease. MPS Type XS Fuse Cutouts are assigned single value nominal voltage ratings (not dual, slant, or system voltage class ratings) and can be applied without restriction on all three-phase systems having system maximum operating voltage (line to line) less than or equal to the cutout maximum voltage. Under certain fault conditions, cutouts can be exposed to voltages in excess of system line-to-neutral voltage fault conditions which the cutout should clear with no reliance on backup devices. Type XS Cutouts have been tested at full system line-to-line voltage across a wide spectrum of available fault currents, using transient recovery voltages representative of those seen in service. Type XS Cutout interrupting ratings have been substantiated by testing performed in accordance with IEEE C Shown on page 2 are asymmetrical and symmetrical interrupting ratings for both three-phase and single-phase applications of Type XS Cutouts. The symmetrical ratings for the overhead pole-top style cutouts are based on an X/R ratio of either 8 or 12, depending on cutout voltage rating and interrupting current rating (as specified by IEEE C ), realistic maximum ratios for locations where cutouts are normally applied on a typical distribution feeder. Higher symmetrical interrupting ratings apply at locations where the X/R ratio is lower. The curves in the chart below indicate the symmetrical ratings of Type XS Cutouts at other X/R ratios. The mechanical construction of the Type XS Cutout is rugged and strong. It is designed to withstand the interruption forces of heavy fault currents and the typically forceful closing-in by operating personnel. The upper contact and the hinge are attached to husky steel supports, and the mounting bracket is attached to a strong mounting insert. The fuse tube is held at the upper contact by a self-aligning springloaded detent-type latch. The detent features silver-clad embossed surfaces for built-in wiping action resulting in minimum electrical resistance between the upper contact and the silverclad fuse-tube cap. The silver-clad lower contacts also feature embossed surfaces for built-in wiping action, and are backed up by prestressed stainless steel loading springs for efficient current transfer between the contacts Table of Contents Polymer Cutouts Porcelain Cutouts Mounting Bracket Options Numerical Index MacLean Power Systems MacLean Power Systems Please note that because MacLean Power Systems follows a policy of continuous product improvement, we reserve the right to change specifications and drawings at any time without notice.

These specially designed high pressure upper and lower contacts, featuring builtin wiping action, assure superb current transfer even after the contacts have been exposed to the atmosphere for an extended period of time. Also applicable on 26.4-kV through 34.5-kV systems for protection of single-phase-to-neutral circuits (lines or transformers) only, and grounded-wye connected capacitor banks in solidly-grounded-neutral (multigrounded-neutral) systems.
