Technical Data 10350 Effective October 2019 Supersedes April 2015 BUSSMANN SERIES 2.75kV E-Rated medium voltage fuses for feeder circuit, switchgear and transformer protection Features and benefits • Current-limiting E-Rated medium voltage fuses are defined by their melting time-current characteristic that permit their electrical interchangeability with other fuses of the same E Rating. • E-Rated fuses must have a defined current response time specified by ANSI C37.46. E-Rated fuse of 100 amps and below must melt in 300 seconds at an RMS current within the range of 200% to 240% of the fuse’s nameplate current rating. E-Rated fuses greater than 100 amps must melt in 600 seconds at an RMS current within the range of 220% to 264% of the fuse’s nameplate current rating. • E-Rated fuses are physically dimensioned for easy installation in existing hardware. • Current-limiting fuses provide positive interruption even on low fault currents. The fuse limits the magnitude of electromechanical stresses in the protected apparatus. • Open fuse indicator speeds troubleshooting by providing a positive visual indication of fuse operation. • 50/60Hz operating frequency for worldwide application. • Mountings are available in disconnect and nondisconnect versions with porcelain or glass polyester insulators. • Live parts and end fittings available. Description: • E-Rated, current-limiting, medium voltage fuses for feeder circuit, switchgear and transformer protection. Typical applications: • Medium voltage transformer primary protection • Medium voltage feeder circuit protection • Medium voltage switches • Medium voltage metal-enclosed switchgear Technical Data 10350 2.75kV E-Rated medium voltage fuses for feeder circuit, switchgear and transformer protection Effective October 2019 2.75kV E-Rated medium voltage ferrule fuses Dimensions (see catalog number tables for values) C Catalog symbols: • 2CLE-_E • JCX-_E B Ratings: • Volts — 2.75kV • Amps — 10 to 450A • Interrupting ratings • 50kA RMS Sym (2CLE-_E) • 3.31 (84.1) B 40kA RMS Sym (JCX-_E) Agency information: • A E-Rated fuses meet the performance characteristics of ANSI C37.46 Recommended fuse holders: CLE Catalog number Approximate dimensions - in (mm) Fuse mounting type* Amp rating Voltage BIL (kV) Diameter A Clip center B Length C Mounting (including live parts, end fittings)** Porcelain insulator Glass-polyester insulator Live parts (including end fittings) End fittings (disconnect only) 2CLE-PNM-C 2CLE-GNM-C CLE-NL-C — 2CLE-PDM-C 2CLE-GDM-C CLE-DL-C CLE-DF-C 2CLE-PNM-D 2CLE-GNM-D CLE-NL-D — 2CLE-PDM-D 2CLE-GDM-D CLE-DL-D CLE-DF-D 2CLE-PNM-E 2CLE-GNM-E CLE-NL-E — 2CLE-PDM-E 5CLE-GDM-E CLE-DL-E CLE-DF-E CLE 15E–25E Single barrel Non-disconnect 60 Disconnect† 60 10E–225E Single barrel Non-disconnect 60 Disconnect† 60 250E–300E 350X-450X Double barrel Non-disconnect 60 Disconnect† 60 2 (51) 8.1 (206) 9.5 (241) 3 (76) 7 (178) 10.9 (277) 3 (76) 7 (178) 10.9 (277) * See page 9 for illustrations and dimensions. ** End fittings supplied only when required. † Disconnect mountings provide a means for fuse extraction only.
