JJN-1 - 1 Amp Fuse Description
JJN-1 - 1 Amp Fuse
When your replacement calls for a 1-amp Class T fuse, the details beyond amperage matter just as much. The JJN-1 Eaton Bussmann series fuse is rated for 1A at 300V, with a 200 kA interrupting rating at 300V AC and a non-indicating configuration. Rather than relying on appearance alone, the JJN-1 provides a clearly documented combination of fuse class, electrical ratings, dimensions, and compliance information to compare with application requirements. It's a straightforward Class T fuse that's built to last while meeting the specific ratings stated for this catalog number.
Key Features and Benefits

Where It Works Best
The JJN-1 1A Class T fuse is best suited for compatible electrical equipment that requires a 1-amp, 300V Class T, non-indicating fuse with an interrupting rating of 200 kA at 300V AC. Also check its 0.88 x 0.41 x 0.41-inch dimensions against the fuse holder and equipment requirements before installation.
A matching JJN-1 catalog number is a good starting point, but it isn't a full compatibility check. Before installation, verify the Class T designation, 1A rating, 300V voltage rating, 200 kAIC rating at 300V AC, non-indicating configuration, dimensions, and equipment requirements. Two fuses that look alike are not necessarily interchangeable. When application requirements are uncertain, a qualified electrical professional should confirm compatibility.
