JTD012 - 12 Amp Fuse

JTD012 - 12 Amp Fuse

The JTD012 is a 12A Class J time-delay fuse for electrical equipment that requires a 12-amp Class J cartridge fuse with a Slo-Blo/Time Lag (T)/Time Delay opening characteristic. Rated for a maximum of 600VAC and 300VDC, the JTD012 is part of the JTD POWR-PRO Fuse family and uses an industrial cartridge configuration. If you're matching a replacement JTD012, the 12A rating is only the starting point. Before determining compatibility, check the fuse class, time-delay characteristic, AC or DC voltage requirements, applicable interrupting capability, cartridge configuration, indicating status, and mounting arrangement against the equipment specifications.
