1 Fusing Equipment Current-Limiting Backup Fuse Electrical Apparatus GENERAL The Cooper Power Systems Current-limiting Backup Fuse is used in series with low current primary protection devices such as a Bay-O-Net Fuse or MagneX Interrupter. The fuse is designed for use in transformer oil, Envirotemp FR3 fluid, or an approved equivalent. The fuse s highly efficient currentlimiting section minimizes the effects of high fault current stresses on equipment and the distribution system. Its minimum interrupting rating is coordinated with that of a low current interrupter to avoid undesirable low current operation; yet its maximum interrupting rating will clear the highest fault currents likely to occur. Higher continuous current ratings can be achieved by connecting two fuses in parallel. application The fuse is used in transformers to protect and isolate faulted equipment. When connected in series with a low current primary protection device, the fuse becomes an element of a twopart protection system that gives a full range of fault protection. This two-part system provides low current protection with the replaceable expulsion fuse or resettable MagneX Interrupter, and it adds the energylimiting protection of a current-limiting fuse. Together, they coordinate easily with upstream and downstream devices. Figure 1. Current-Limiting Backup Fuse. installation No special tools are required. The fuse is liquid immersed, mounted as near as possible to the incoming primary bushing to which it is connected. Normal liquid dielectric clearances should be used. Refer to Installation Instructions Sheet S for details. PRODUCTION TESTS Tests are conducted on 100 percent of production in accordance with Cooper Power Systems requirements.

2 Current-Limiting Backup Fuse HIGH PURITY SILICA SAND FILLER Specific particle size, purity, and compaction gives the heat-absorbing and arc-quenching properties necessary for consistent clearing and low energy let-thru levels. MICA SPIDER Provides stable winding support without generating gas and pressure buildup during fuse operation. A B C SOLID COPPER END CAPS Brass inserts are tapped for attachment of a 1 /4 inch - 20 x 1 /2 inch lead hardware. DOUBLE SEALING SYSTEM Buna-N rubber gasket and epoxy sealant ensures seal performance and integrity. FIBERGLASS HOUSING Provides strength and maintains integrity of fuse during any interruption, from minimum melt current to maximum rated current of ka. INDELIBLE IDENTIFICATION LABEL Easy-to-read voltage and current ratings and catalog numbers. FUSE ELEMENT Stable under current cycling and thermal stress, providing consistent melt characteristics. The ribbons effectively control and minimize peak arc voltage levels resulting from high current interrup tions. During inter rup tion, the element effectively controls and limits both current and energy (l 2 t) let-thru levels.

14 Current-Limiting Backup Fuse Application peak let-through current Maximum peak let-thru curves provide the opportunity of comparing an unprotected system of one protected with an expulsion fuse, boric acid fuse or recloser to a system protected with current-limiting backup fuse. For example, as shown in Figure 4, an unprotected circuit with a 10,000 A available fault current can deliver a maximum peak current to a fault of about 28,000 A (find the intersection of the 10,000 A available current line with the peak current line, and read the result on the left maximum letthru axis). This would be the current delivered, regardless of the size of any expulsion fuse that could be applied. Protecting this apparatus with a 15.5 kv, A, fuse however, would limit the peak let-thru current to the apparatus to about 8,000 A. This is the same peak let-thru delivered to a fault by a system having only 40 A available current. Figure 4.
