JTD070 - 70 Amp Fuse

JTD070 - 70 Amp Fuse

The JTD070 is a 70A Class J time-delay fuse designed for electrical equipment that calls for this specific combination of current rating, fuse class, opening characteristic, voltage capability, and physical format. Rated up to 600VAC and 300VDC, it uses Slo-Blo/Time Lag (T)/Time Delay operation and a knife-blade construction. The JTD070 is part of the JTD Series and POWR-PRO Fuse family, and this particular catalog number is non-indicating. If you're evaluating the JTD070 as a replacement, don't stop at the 70A marking. Check the Class J designation, time-delay characteristic, AC or DC voltage requirements, applicable interrupting rating, knife-blade configuration, non-indicating design, and mounting compatibility against the equipment specifications.

Material Compliance and Certifications

The manufacturer information supplied for the JTD070 confirms its electrical and physical specifications, including the 70A continuous current rating, Class J classification, time-delay opening characteristic, voltage ratings, interrupting values, knife-blade construction, non-indicating configuration, and mounting method.

Where It Works Best

The JTD070 best matches electrical equipment designed for a 70A Class J time-delay fuse with the corresponding electrical and physical requirements. For AC service, confirm the equipment requirements against the fuse's 600VAC maximum rating and the applicable AC interrupting value. For DC service, the supplied specifications identify a 300VDC maximum rating and a 20 kA interrupting rating at 300VDC.
