JKS-400 - 400 Amp Fuse Description
JKS-400 - 400 Amp Fuse
A 400-amp fuse leaves little room for casual part selection—the electrical ratings, fuse class, connection style, and physical dimensions must match the equipment. The Eaton Bussmann series JKS-400 is a 400A, 600V Class J fuse with a manufacturer-specified 200 kAIC interrupting rating at 600VAC. When your electrical application calls for these characteristics, the JKS-400 provides clear specifications you can verify before installation. It’s built to last, but selecting the right fuse is simple: make sure the full specification matches the equipment requirements, not just the 400A rating.
Key Features and Benefits
- 400A amperage rating: Clearly specified for compatible electrical equipment requiring a 400-amp fuse.
- 600V voltage rating: Provides a defined voltage specification for application and replacement checks.
- Class J fuse: Identifying the fuse class helps narrow the selection beyond amperage and voltage alone.
- Single element: The manufacturer specifies one element for the JKS-400.
- Non-indicating design: This fuse does not provide a visual blown-fuse indication.

The supplied manufacturer specifications identify the JKS-400 as RoHS-compliant. This provides documented material-compliance information for applications where RoHS status matters.
Where It Works Best
The JKS-400 400A 600V Class J fuse is best suited for compatible electrical equipment that requires a 400A Class J fuse rated at 600V with a 200 kAIC interrupting rating at 600VAC. Its single-element construction, non-indicating configuration, bolted blade-end connections, and 7.13 x 2 x 2-inch dimensions should also match the equipment and fuse mounting arrangement.
