E rated power fuses

Web• NEMA Standards for E-rated MV power fuses require that fuses rated 100E or less open within 300 seconds (5 minutes) when subjected to an RMS (root-mean-squared) current of 200-240% of the fuse’s continuous current rating. Fuses with an “E” rating larger than 100E must open within 600 seconds (10 minutes) when subjected to an RMS WebWoodland Park, NJ. 86 Lackawanna Ave, Ste 240 Woodland Park, NJ 07424. 888-840-FUSE (3873)
