JFL400 - 400Amp Fuse

JFL400 - 400Amp Fuse

When you're working with a 400-amp fuse, don't focus only on the amperage. Eaton's Edison JFL400 is a great example. This Class J fuse is rated for 400 amps at 600 volts and has a 200 kAIC interrupting rating. It's built to last, and its specs make compatibility easy to check. For replacements, always verify the complete specs instead of relying on appearance alone!

Key Features and Benefits

• 400A rating: Designed for compatible electrical equipment requiring a 400-amp Class J fuse.
• 600V voltage rating: Provides a clearly documented voltage specification for matching against equipment requirements.
• Class J fuse: Makes the fuse classification clear when identifying the correct replacement component.
• Non-indicating configuration: Suitable where the equipment specification calls for this particular fuse configuration.

Where It Works Best

The JFL400 is intended for compatible electrical equipment requiring a 400A, 600V Class J fuse with a 200 kAIC interrupting rating and non-indicating configuration. Also check its 7.13 x 2 x 2-inch dimensions against the equipment's physical requirements.

A matching catalog number is the starting point, not the whole compatibility check. Before replacing an existing fuse with the JFL400, verify the fuse class, amperage, voltage, interrupting rating, dimensions, and equipment requirements. Similar appearance alone does not establish interchangeability. If you are unsure about application or compatibility, a qualified electrical professional should verify it.
