JJN-50 - 50Amp Fuse

JJN-50 - 50 Amp Fuse

Even a small fuse still has a specific compatibility checklist. The Eaton Bussmann series JJN-50 is a 50-amp Class T fuse rated for 300VAC and 160VDC, with a 200 kAIC interrupting rating at 300VAC and 20 kAIC at 160VDC. For electricians, maintenance teams, and facility professionals trying to identify the right replacement, these documented specifications make the evaluation much simpler. Check the current rating, voltage, interrupting rating, Class T designation, dimensions, and connection style against your equipment requirements.

Key Features and Benefits

• 50A Class T fuse with clearly defined electrical and physical specifications.
• Rated for 300VAC and 160VDC, allowing compatibility to be evaluated for the applicable AC or DC system.
• The ferrule-to-ferrule connection makes the termination style easy to compare with the existing fuse and fuse holder.
• Non-indicating design with no built-in visual fuse-status indicator.
• Eaton Bussmann catalog number JJN-50 and UPC/EAN identifiers provide precise references for product identification.

Material Compliance and Certifications

The supplied manufacturer information identifies the JJN-50 as CE-marked and RoHS-compliant. These are the documented compliance designations for this specific catalog number.

The manufacturer did not provide UL, CSA, REACH, or other certification information for the JJN-50. Do not assume those designations based on other products in the same series.

Where It Works Best

The Eaton Bussmann JJN-50 50A Class T fuse is best suited to existing electrical equipment that specifically requires a 50A Class T fuse and accommodates its ferrule-to-ferrule connection and 0.86 x 0.57 x 0.57-inch dimensions. For an AC application, confirm the equipment requirements against the fuse's 300VAC rating and 200 kAIC interrupting rating at 300VAC. For a compatible DC application, compare them with the 160VDC rating and 20 kAIC interrupting rating at 160VDC.
