JJN-80 - 80Amp Fuse

JJN-80 - 80Amp Fuse

If you already have JJN-80 on your maintenance list, the next step is to make sure the electrical ratings and physical configuration match the equipment. The Eaton Bussmann series JJN-80 is an 80-amp Class T fuse rated for 300VAC and 160VDC. It is non-indicating, meaning there is no built-in visual indicator to show fuse status. For electricians, maintenance departments, and facility teams, that combination of ratings, dimensions, and connection details gives you a straightforward way to compare this fuse with the component being replaced.

Key Features and Benefits

• 80A Class T fuse with a clearly defined current rating for compatibility checks.
• Rated for both 300VAC and 160VDC applications where the equipment requirements correspond to these ratings.
• The bolted blade-end-to-bolted-blade-end configuration makes the required connection style easy to identify.
• Non-indicating design means the fuse does not include a built-in visual status indicator.
• CE-marked and RoHS-compliant according to the supplied manufacturer specifications.
• Exact JJN-80 catalog identification helps maintenance personnel distinguish it from other Class T fuse ratings.

Where It Works Best

The JJN-80 80A Class T fuse is best suited to compatible existing electrical equipment that calls for this particular combination of 80A current rating, Class T configuration, 300VAC or 160VDC voltage rating, corresponding interrupting capacity, bolted-blade connection, and physical dimensions. It can be especially straightforward to evaluate when JJN-80 appears in the equipment documentation or when the replacement fuse provides enough information for a complete specification comparison.
