It may also be used to protect power transformers, feeders and other equipment that can benefit from its energy-limiting properties. The fuse provides consistent clearing of low currents as well as reliable high speed interruption of high magnitude short circuit currents. Its current-limiting capability limits both peak current magnitude and fault duration, thus limiting the let-through energy. ELSG fuses have both the low current and high current clearing sections in one housing. This eliminates expulsion byproducts discharging into the oil when the fuse operates. Concerns associated with miscoordination of separate expulsion and current-limiting fuse sections in the field are eliminated. Also, field testing the current-limiting section when the expulsion section operates is also eliminated. The E-rated ELSG fuses have timecurrent characteristics that coordinate easily with other upstream and downstream protective devices. The MSLE version of the ELSG fuses are interchangeable with the K-MATE™ SL (A.B. Chance) assembly. ELSG fuses have been tested and meet all requirements set forth in ANSI/IEEE C37.40, C37.41, and C37.46 Standards. Double-Barrel Fuse Assembly Triple-Barrel Assembly Fuse Figure 1.
