JJN-20 - 20Amp Fuse

JJN-20 - 20 Amp Fuse

A replacement fuse has to satisfy both sides of the equation: the electrical ratings and the physical fit. The Eaton Bussmann series JJN-20 is a 20A Class T fuse rated for 300VAC and 160VDC, with corresponding interrupting ratings of 200 kAIC at 300VAC and 20 kAIC at 160VDC. When your equipment documentation calls for a 20-amp Class T fuse, the JJN-20 gives you a clearly documented set of specifications to work from, rather than relying on appearance alone. It's built to last, with the practical electrical and physical details needed to make an informed compatibility check.

Key Features and Benefits

• 20A Class T fuse: A clearly defined amperage and fuse class simplify replacement identification.
• AC and DC ratings: Rated for 300VAC and 160VDC, allowing the applicable rating to be checked against the intended system.
• Ferrule connections: Features a ferrule end x ferrule end configuration that can be compared directly with the fuse connection required by the equipment.
• Non-indicating design: Does not incorporate a visual fuse-status indicator.

Where It Works Best

The JJN-20 20A Class T fuse suits compatible electrical equipment that requires its specific combination of 20A current rating, 300VAC or 160VDC voltage rating, applicable interrupting rating, ferrule-to-ferrule connection, and compact physical dimensions. For AC applications, the documented interrupting rating is 200 kAIC at 300VAC; for DC applications, it is 20 kAIC at 160VDC.
