JJN-450 - 450Amp Fuse Description
JJN-450 - 450Amp Fuse
If your equipment documentation calls for a 450-amp Class T fuse, the next step is to make sure every key detail matches the application. The Eaton Bussmann series JJN-450 is rated at 450A, 300VAC, and 160VDC, with an interrupting rating of 200 kAIC at 300VAC and 20 kAIC at 160VDC.
Key Features and Benefits
- 450A Class T fuse for equipment requiring this specific fuse class and current rating.
- Dual voltage ratings of 300VAC and 160VDC provide clearly defined specifications for applicable AC and DC systems.
- Bolted blade connections on both ends provide a specific physical configuration that can be checked against the existing installation.
- The non-indicating design means the fuse has no built-in visual fuse-status indicator.
- Catalog number JJN-450 gives maintenance personnel a precise reference when comparing the fuse with equipment documentation.

Material Compliance and Certifications
The supplied manufacturer specifications identify the JJN-450 as CE-marked and RoHS-compliant. These are the compliance designations documented for this particular catalog number.
No UL, CSA, REACH, or other certification information was supplied for the JJN-450. Do not assume those designations simply because they may appear on other products in the same fuse family.
Where It Works Best
The Eaton Bussmann JJN-450 450A Class T fuse is best considered for existing electrical equipment that specifically calls for a 450A Class T fuse with the appropriate 300VAC or 160VDC rating. Also ensure the required interrupting rating matches the application: 200 kAIC at 300VAC or 20 kAIC at 160VDC.
Don't overlook the physical side of the compatibility check. The equipment must accommodate the JJN-450's 3.06 x 1.25 x 1.25-inch dimensions and its bolted blade connection at both ends. Because this model is non-indicating, use it where that configuration is appropriate.
