JTD050 - 50 Amp Fuse

JTD050 - 50 Amp Fuse

The JTD050 is a 50A Class J time-delay fuse in an industrial cartridge configuration for electrical equipment that requires this specific combination of current rating, fuse class, voltage capability, and opening characteristic. Rated for a maximum of 600VAC and 300VDC, the JTD050 uses a Slo-Blo/Time Lag (T)/Time Delay opening characteristic and belongs to the JTD Series and POWR-PRO Fuse family. If you're replacing an existing JTD050, don't stop after matching the 50A marking. Also check the Class J designation, time-delay characteristic, AC or DC voltage requirement, applicable interrupting rating, non-indicating configuration, cartridge format, and mounting requirements.
