JTD070-ID - 70 Amp Fuse

JTD070-ID - 70 Amp Fuse

When your replacement calls for an indicating 70A Class J time-delay fuse, matching the complete specification matters—not just the amp rating. The JTD070-ID, manufacturer catalog reference JTD070ID, is a 70-amp Class J fuse with Slo-Blo/Time Lag (T)/Time Delay operation and a knife-blade construction. For a proper replacement match, confirm the Class J designation, 70A rating, time-delay characteristic, voltage requirements, applicable interrupting rating, indicating design, knife-blade format, and mounting requirements.

Key Features and Benefits

• 70A continuous current rating for equipment specified for a 70-amp fuse

Material Compliance and Certifications

The supplied manufacturer specifications establish the JTD070-ID's Class J designation, 70A continuous current rating, time-delay opening characteristic, 600VAC and 300VDC maximum voltage ratings, interrupting values, knife-blade construction, indicating status, mounting method, and specified holder family.

Where It Works Best

The JTD070-ID 70A Class J time-delay indicating fuse suits electrical equipment designed for a 70A Class J fuse with time-delay operation and an indicating configuration. For AC installations, compare the equipment requirements with the fuse's 600VAC maximum rating and the applicable AC interrupting requirement. For DC service, the supplied specifications identify a 300VDC maximum rating and a 20 kA interrupting rating at 300VDC.
