JJN-25 - 25Amp Fuse

JJN-25 - 25 Amp Fuse

When you’re working with a compact fuse, a few numbers can make the difference between the right component and one that looks right. The Eaton Bussmann series JJN-25 is a 25-amp Class T fuse rated for 300VAC and 160VDC. It is also non-indicating, so there is no visual fuse-status indicator. For maintenance teams, electricians, and facility professionals trying to find an exact replacement, these documented specifications remove much of the guesswork. Built to last, it provides straightforward electrical and dimensional details to check before installation.

Key Features and Benefits

• 25A Class T fuse: The clearly defined amperage and fuse class make it easier to match the JJN-25 to equipment requirements.
• AC and DC ratings: Rated for 300VAC and 160VDC, with separate interrupting ratings for each stated voltage.
• Ferrule-to-ferrule connection: Ferrule ends on both sides provide a clearly specified connection configuration to compare with the existing fuse and equipment.
• Non-indicating: Designed without a visual fuse-status indicator.

Material Compliance and Certifications

The manufacturer lists the JJN-25 as CE-marked and RoHS-compliant. These documented compliance details can be especially useful when checking components against project, facility, or equipment requirements.

Where It Works Best

The JJN-25 25A Class T fuse is best evaluated for existing electrical equipment that specifically calls for its combination of 25A amperage, Class T configuration, voltage ratings, interrupting ratings, ferrule-end connections, and compact dimensions. For AC equipment, compare the application requirements with its 300VAC rating and 200 kAIC interrupting rating. For DC equipment, the corresponding specifications are 160VDC and 20 kAIC.
