JJN-500 - 500Amp Fuse

JJN-500 - 500Amp Fuse

For your 500-amp Class T fuse, the connection style and physical dimensions deserve just as much attention as the electrical ratings. The Eaton Bussmann series JJN-500 is rated at 500A, with voltage ratings of 300VAC and 160VDC. Rather than relying on appearance or amperage alone, compare the full set of ratings and dimensions with the application. The JJN-500 is built to last and provides clearly documented specifications, making a careful compatibility check straightforward.

Key Features and Benefits

• 500A Class T fuse for equipment requiring this specific current rating and fuse class.
• Dual voltage ratings: 300VAC and 160VDC.
• Bolted blade connections on both ends provide a clearly defined connection configuration for fit verification.
• Non-indicating design means fuse status is not shown through a built-in visual indicator.
• Catalog number, UPC, dimensions, and electrical ratings provide multiple reference points for accurate product identification.
