JJN-3 - 3Amp Fuse

JJN-3 - 3Amp Fuse

Need a 3-amp Class T fuse and want to make sure the details line up before installation? The Eaton Bussmann JJN-3 series is rated at 300V and has a 200 kAIC interrupting rating at 300VAC. If JJN-3 is the catalog number you're replacing, you already have a useful starting point. From there, compare the 3A rating, Class T designation, voltage, interrupting rating, and physical size with your equipment's requirements. It's built to last and gives maintenance teams and electricians a clearly defined set of specifications to work from.

Key Features and Benefits

• 3A Class T fuse for equipment requiring this specific current rating and fuse class.
• Rated for 300V, giving you a clear electrical specification to verify against the application.
• Non-indicating configuration without a built-in visual fuse-status indicator.
• Catalog number JJN-3 helps identify the exact model during maintenance and replacement work.

Material Compliance and Certifications

No UL, CSA, REACH, or other certification information was provided for this particular catalog number. Do not assume those certifications simply because they may appear on other products in the same general product family.

Where It Works Best

The JJN-3 makes sense when your existing equipment calls for a 3A, 300V Class T fuse with a 200 kAIC interrupting rating at 300VAC and the physical dimensions match the available fuse position. Its compact size also makes dimensional verification particularly important—something worth checking rather than judging by appearance.
