JJN-200 - 200Amp Fuse

JJN-200 - 200Amp Fuse

When you're replacing a 200-amp Class T fuse, there are a few details you want to get right the first time. The Eaton Bussmann series JJN-200 is rated for 300VAC and 160VDC, with an interrupting rating of 200 kAIC at 300VAC and 20 kAIC at 160VDC. For maintenance teams, electricians, and equipment owners looking for this Class T configuration, clearly documented electrical ratings, connection style, and compact dimensions make compatibility checks easier. Built to last, it provides the specific product information you need without relying on assumptions based on appearance.

Key Features and Benefits

• 200A Class T fuse: Provides a clearly defined amperage and fuse class for accurate component identification.

Where It Works Best

The JJN-200 200A Class T fuse is best evaluated for existing electrical equipment that specifically calls for a 200A Class T fuse with the JJN-200's documented ratings and physical configuration. That means checking the 300VAC or 160VDC voltage requirement, the applicable 200 kAIC AC or 20 kAIC DC interrupting rating, the bolted blade connections, and the 2.44 x 0.88 x 0.88-inch dimensions.
