JTD045 - 45 Amp Fuse

JTD045 - 45 Amp Fuse

A 45A rating gets you into the neighborhood, but it doesn't tell you whether a fuse is the right replacement. The JTD045 is a 45-amp Class J time-delay fuse built in an industrial cartridge format, with maximum ratings of 600VAC and 300VDC. Its opening characteristic is specified as Slo-Blo/Time Lag (T)/Time Delay, and it belongs to the JTD POWR-PRO Fuse family. This particular model is non-indicating, an easy detail to overlook when you're comparing similar Class J fuses.
