1 8.3kV E-Rated Description: E-Rated, current-limiting, medium voltage fuses for feeder circuit, switchgear and transformer protection. Supersedes pril 2015 USSMNN SERIES Medium voltage fuses for feeder circuit, switchgear and transformer protection Features and benefits: urrent-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 NSI 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. urrent-limiting fuses provide positive interruption even on low fault currents. The fuse limits the magnitude of electromechanical stresses in the protected apparatus. onstructions available in ferrule, bolt-on and clip lock, and specialty mount fuses for MPGRD motor starters. Outdoor rating available on select catalog numbers (requires installation in a suitable enclosure). Open fuse indicator easily integrates into automation schemes and speeds troubleshooting by providing a positive visual indication of fuse operation. 50/60Hz operating frequency for worldwide application. Mountings are available in disconnect and non-disconnect versions with porcelain or glass polyester insulators. Live parts and end fittings available. Typical applications: Medium voltage transformer primary protection Medium voltage feeder circuit protection Medium voltage switches Medium voltage metal-enclosed switchgear
