JJN-125 - 125Amp Fuse

JJN-125 - 125Amp Fuse

When you're tracking down a 125-amp Class T fuse, amperage is only the beginning of the compatibility check. The Eaton's Bussmann JJN-125 is rated for 300VAC and 160VDC, with an interrupting rating of 200 kAIC at 300VAC and 20 kAIC at 160VDC. Straightforward specifications, a compact Class T format, and clearly documented ratings make this a practical component to evaluate when the equipment calls for this exact configuration. Built to last, it gives maintenance professionals the key information they need to make an informed compatibility check.

Key Features and Benefits

• 125A Class T design: A clearly defined current rating and fuse class make it easier to compare against equipment requirements.
• Rated for AC and DC applications: Manufacturer ratings are 300VAC and 160VDC.
• Bolted blade ends: Uses a bolted blade end x bolted blade end connection rather than a ferrule-style connection.
• Non-indicating: Designed without a built-in visual fuse-status indicator.

Material Compliance and Certifications

According to the supplied manufacturer specifications, the JJN-125 is CE Marked and RoHS Compliant.

No UL, CSA, REACH, or other certification information was supplied for this particular catalog number. Don't assume those certifications just because they appear on other products in the same series. When a specific approval is required, check the fuse markings and applicable manufacturer documentation.

Where It Works Best

The JJN-125 makes sense for existing electrical equipment that calls for a 125A Class T fuse with the corresponding voltage and interrupting ratings. Its bolted blade connection and physical dimensions are equally important when checking whether it fits the intended application.

For AC equipment, compare the system requirements with the JJN-125fuse's 300VAC rating and 200 kAIC interrupting rating at 300VAC. For DC equipment, the applicable manufacturer ratings are 160VDC and 20 kAIC at 160VDC.
