JJN-300 - 300Amp Fuse

JJN-300 - 300Amp Fuse

When your equipment calls for a 300-amp Class T fuse, getting the details right means looking beyond amperage alone. The Eaton Bussmann series JJN-300 is rated for 300VAC and 160VDC, with an interrupting rating of 200 kAIC at 300VAC and 20 kAIC at 160VDC.

Key Features and Benefits

• 300A Class T fuse with clearly documented electrical and physical characteristics.
• Rated for 300VAC and 160VDC, allowing compatibility to be evaluated against the applicable AC or DC equipment requirements.
• Bolted blade-end x bolted blade-end connection provides a specific configuration to verify against the existing fuse installation.
• Non-indicating design with no built-in visual fuse-status indicator.
• CE Marked and RoHS Compliant according to the supplied manufacturer specifications.

Material Compliance and Certifications

The supplied manufacturer information identifies the JJN-300 as CE-marked and RoHS-compliant. These are the compliance designations documented for this specific catalog number.

No UL, CSA, REACH, or additional certification information was provided for the JJN-300, so do not assume those designations simply because they may appear on other products in the broader fuse family.

Where It Works Best

The JJN-300 300A Class T fuse is best suited to compatible electrical equipment specifically requiring its combination of 300A current rating, 300VAC or 160VDC voltage rating, corresponding interrupting capacity, bolted-blade connection, and physical dimensions. That makes it important to compare the full specification set when replacing an existing fuse, rather than choosing a component based on amperage or appearance alone.
