JJN-45 - 45Amp Fuse

JJN-45 - 45 Amp Fuse

A fuse may take up very little space inside electrical equipment, but the details printed on it carry a lot of weight. The Eaton Bussmann series JJN-45 is a 45A Class T fuse rated for 300VAC and 160VDC, with an interrupting rating of 200 kAIC at 300VAC and 20 kAIC at 160VDC. For an electrician or maintenance professional confirming the right replacement, these specifics are far more useful than appearance alone. When your equipment calls for this exact combination of Class T, amperage, voltage, interrupting capacity, connection, and dimensions, the JJN-45 gives you a clearly defined component that's built to last.

Key Features and Benefits

• 45A Class T fuse with clearly documented electrical and physical characteristics.
• Rated for both 300VAC and 160VDC applications when those ratings match the equipment requirements.
• The ferrule-to-ferrule connection makes the physical configuration straightforward to verify.
• Non-indicating design for applications that specify this fuse configuration.
• Exact JJN-45 catalog identification makes it easier to compare against equipment documentation or an existing fuse.

Where It Works Best

The Eaton Bussmann JJN-45 45A Class T fuse suits compatible electrical equipment that requires a 45-amp Class T fuse, a 300VAC or 160VDC rating, the corresponding interrupting capacity, and a ferrule-to-ferrule connection. Its compact dimensions also matter: check 0.86 x 0.57 x 0.57 inches against the available fuse position and the equipment specifications.
