JTD003 - 3 Amp Fuse

JTD003 - 3 Amp Fuse

When the equipment calls for a 3A Class J time-delay fuse, getting the details right matters just as much as matching the amperage. The JTD003 is a 3-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 a replacement JTD003, don't stop after confirming "3 amps." Fuse class, time-delay operation, AC or DC voltage, interrupting capability, cartridge configuration, and mounting method should all match the equipment requirements.

Material Compliance and Certifications

The supplied product information identifies the JTD003 as a 3A Class J time-delay fuse in the JTD POWR-PRO family. The manufacturer data provides its primary electrical and installation specifications, including the AC and DC voltage ratings, interrupting values, industrial cartridge construction, non-indicating configuration, and mounting method.

Where It Works Best

The JTD003 3A Class J fuse suits electrical equipment that specifically requires a 3-amp Class J fuse with time-delay operation. For AC installations, verify that the circuit and equipment requirements are within the 600VAC maximum rating and match the applicable interrupting requirements. For DC use, the supplied specifications provide a maximum rating of 300VDC and an interrupting rating of 20 kA at 300VDC.

Physical compatibility counts, too. The JTD003 uses an industrial cartridge configuration and is intended for installation in a compatible fuse block, clip, or holder; the LFPSJ30 Series is the corresponding holder family. When using the JTD003 as a replacement, compare the full specification—3A current rating, Class J classification, time-delay characteristic, AC/DC voltage ratings, interrupting capability, non-indicating configuration, cartridge format, and mounting arrangement—with the equipment requirements.
