JTD090 - 90 Amp Fuse

JTD090 - 90 Amp Fuse

The JTD090 is a 90A Class J time-delay fuse for equipment that calls for this specific combination of current rating, fuse class, voltage capability, opening characteristic, and physical configuration. Rated for a maximum of 600VAC and 300VDC, it features Slo-Blo/Time Lag (T)/Time Delay operation and knife-blade-style construction. If you're checking the JTD090 as a replacement, matching the 90A rating is only the beginning. The Class J designation, time-delay characteristic, AC/DC ratings, interrupting requirements, non-indicating design, knife-blade format, and mounting compatibility should all agree with the equipment specifications.
