This range of characteristics is offered in part by the production of both expulsion and currentlimiting power fuses. Expulsion and current-limiting fuses provide such diverse characteristics by employing different areas of fuse technology. These differences in technology, along with the diverse characteristics, require that different questions be answered when applying expulsion and currentlimiting fuses. Product History The Eaton power fuse product line was introduced in the 1930s by Westinghouse Electric Corporation. As power systems grew in size, the need to sectionalize utility feeders and to protect equipment became apparent. The initial fuse development efforts resulted in the creation of non-current-limiting, expulsion type fuses. As the available fault currents grew, the need for a current-limiting fuse was apparent and this resulted in new interruption techniques. While basic fuse technology has not changed greatly over the years, gradual improvements have been made to make the fuses more current-limiting and easier to manufacture and install. Because standards for fuses (ANSI C37) detail only test methods and basic performance requirements, many different varieties of fuses (length, diameter, shortcircuit interruption curves) have been introduced over the years. Eaton presently manufactures medium voltage fuses in Haina, DR.

Fuse rated above 100E will melt in 600 seconds at a current value between 2.2 and 2.64 times the E number. If the current is higher than 2.4 or 2.64 times the E number, the user must consult the time-current curves for that particular fuse. “R” Designation The fuse will melt in 15 to 35 seconds when the current equals 100 times the R number. If the current is higher than 100 times the R number, the user must consult the timecurrent curves for that fuse. “C” Designation The fuse will melt in 1000 seconds at a current value, between 1.7 and 2.4 times the C number. 12 13 If the current is higher than 2.4 times the C number, the user must consult the time-current curves for that particular fuse. 14 “A” Designation Fuses that do not comply with “E,” “R” or “C” designations. 16 Expulsion fuses can also be E-rated, K-rated and T-rated, and are also covered in the ANSI standards. The K and T ratings refer, respectively, to relatively “fast” and “slow” melting expulsion fuses. Detailed time-current tables adequately define these ratings. 15 17 18 19 20 21 22 23 24 25 Volume 12—Aftermarket, Renewal Parts and Life Extension Solutions CA08100014E—October 2016 www.eaton.com V12-T18-3 18 1 Medium Voltage Fuses Current-Limiting Fuses Current-Limiting Fuses 2 3 4 5 CLE and HLE Current-Limiting—E-Rated 6 8 10 CLPT Current-Limiting E-Rated for Potential Transformer Protection 11 12 13 14 General Information Current-limiting fuses are constructed with pure silver fuse elements, a high-purity silica sand filler, a specially designed core and a glass resin outer casing. Applications Current-limiting technologies can be used to meet almost every fuse application. Typical applications for utility, industrial, construction and OEM customers include: A high fault current melts the silver element almost instantly and loses energy to the surrounding sand. The sand melts and forms fulgurite, a glass-like substance. The arc voltage rapidly increases to nearly three times the fuse voltage rating and forces the current to zero. Low fault current melts a solder drop on the silver fuse element that, in turn, melts the silver. 7 9 Product Description CLS Current-Limiting for Motor Starter 15 16 The element burns back until there is a sufficient internal gap to interrupt the current. This is known as the M-effect. Eaton current-limiting fuses are offered in two basic types: backup and general purpose. Backup fuses have a published minimum interrupting current and require a series device for breaking the circuit for currents below this minimum level. General purpose fuses have improved low current interruption capability and are designed to interrupt low fault currents that cause the fuse to melt in one hour or less. ● ● ● ● ● ● ● ● ● ● ● Feeder circuit sectionalizing Power transformers Substation service transformers Underground distribution transformers Pole-mounted transformers Pad-mounted distribution transformers Fused switches DIP poles Motor starters Potential transformers Substation capacitor banks Accessories A wide assortment of mountings, live parts and end fittings are available to facilitate power fuse installation. Mountings include a base, porcelain or glass polyester insulators and live parts. They help enable the fuse to be safely attached to the gear. Mountings can be either disconnect or nondisconnect. Live Parts attach the fuse to the mountings and are considered part of the mounting. All parts above the insulators are live parts. Live Parts End Fittings are metal parts that attach to each end of the fuse at the ferrules. They are used only on disconnect fuses or when converting a nondisconnect to a disconnect fuse. 17 18 19 CX Current-Limiting—Interchangeable with McGraw Edison’s NX Type 20 21 22 23 CLT Current-Limiting for Transformer Protection 24 25 V12-T18-4 Volume 12—Aftermarket, Renewal Parts and Life Extension Solutions CA08100014E—October 2016 www.eaton.com Medium Voltage Fuses Expulsion Fuses Expulsion Fuses RBA—Refillable Boric Acid RDB—Refillable Dropout Boric Acid DBU—Dropout Boric Acid— Interchangeable with S&C’s SMU-20 Product Description Eaton expulsion fuses use boric acid as the interrupting medium. Under a fault condition, arc heat decomposes the boric acid, which produces gases and boric anhydride. The water vapor blast extinguishes the arc in a deionizing action and exits from the bottom of the fuse. Type RBA indoor expulsion fuses are fitted with a filter or condenser that moderates the discharge exhaust. The discharge filter limits the exhaust to a small and relatively inert amount of gas and lowers the noise level without affecting the fuse interrupting rating. Steam discharge, that can affect the interrupting, is fully restricted by the condenser. Each type RDB outdoor dropout fuse includes an ejector pin that is forced through the top of the fuse. The ejector pin releases a latch on the mounting and the fuseholder is kicked outward and swings into the dropout position, through 180° with a vertical mounting, or 90° with an underslug mounting. Refill units can be field installed into RBA and RDB expulsion fuses. Once the old unit has been removed, the separately purchased unit can be easily installed into the fuse holder. General Information Applications Expulsion technologies can be used to meet a number of fuse applications. Typical applications for utility, industrial construction and OEM customers include: ● ● ● ● ● ● ● Feeder circuit sectionalizing Fused switches Power transformers Substation service transformers DIP poles Potential transformers Substation capacitor banks 18 Accessories The following accessories are available for expulsion fuses: Mountings include a base, porcelain or glass polyester insulators and live parts. They help enable the fuse to be safely attached to the gear. Mountings can be either disconnect, nondisconnect or dropout. Fuses may be vertical or underhung. Live Parts attach the fuse to the mountings and are considered part of the mounting. All parts above the insulators are live parts. End Fittings must be mounted on DBU fuse units to enable them to be fitted into the mounting. Filters and Condensers are for indoor applications of RBA expulsion fuses. They confine the arc within the fuse and substantially reduce the noise and exhaust when the fuse interrupts. Mufflers are used with DBU fuses in indoor applications to virtually eliminate offensive noise and exhaust gases when the fuse interrupts. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 Volume 12—Aftermarket, Renewal Parts and Life Extension Solutions CA08100014E—October 2016 www.eaton.com V12-T18-5 18 1 2 3 4 5 6 7 10 11 12 13 14 15 16 Current-Limiting and Expulsion Fuses Product Selection Easy to Use, Easy to Order!
