JTD004 - 4 Amp Fuse

JTD004 - 4 Amp Fuse

When you're looking for a 4A Class J time-delay fuse, amperage is only the first specification to check. The JTD004 is a 4-amp industrial cartridge fuse with a Slo-Blo/Time Lag (T)/Time Delay opening characteristic, a maximum rating of 600VAC, and a maximum rating of 300VDC. If you're matching an existing JTD004 or checking compatibility for another application, compare the complete specification rather than simply looking for "4A." Fuse class, AC or DC voltage, applicable interrupting rating, time-delay characteristic, cartridge configuration, and mounting method should all agree with the equipment requirements.
