JTD030 - 30 Amp Fuse

JTD030 - 30 Amp Fuse

When you're replacing a fuse, 30 amps is only the starting point. The JTD030 is a 30A Class J time-delay fuse with an industrial cartridge design and maximum ratings of 600VAC and 300VDC. Its opening characteristic is listed as Slo-Blo/Time Lag (T)/Time Delay, and it belongs to the JTD POWR-PRO Fuse family. The JTD030 installs in a compatible fuse block, clip, or holder; the LFPSJ30 Series is the specified holder family. So, before making the match, look beyond the 30A rating. Fuse class, time-delay operation, voltage, interrupting requirements, physical format, and mounting all matter.
