JKS-250 - 250 Amp Fuse

JKS-250 - 250 Amp Fuse

At 250 amps, a proper fuse match involves more than matching the label number. The Eaton Bussmann series JKS-250 is a 250A, 600V Class J fuse with a manufacturer-specified interrupting rating of 200 kAIC at 600VAC. For maintenance, repair, or replacement work where the equipment documentation calls for these characteristics, the JKS-250 provides clear specifications you can verify before installation. It's built to last, but proper application still comes down to confirming the complete electrical rating, connection format, fuse class, and physical fit—not simply matching the amperage.

Key Features and Benefits

• 250A amperage rating: Designed for compatible equipment requiring a 250-amp fuse.
• 600V rating: Provides a clearly specified voltage rating for accurate application matching.
• Class J configuration: Helps identify the required fuse class when checking equipment documentation or an existing fuse.
• Single-element design: The JKS-250 is specified as a single-element fuse.
• Non-indicating: Straightforward non-indicating fuse configuration with no visual fuse-status indicator specified.

Where It Works Best

The JKS-250 250A 600V Class J fuse suits compatible electrical equipment whose specifications call for a 250A Class J fuse rated at 600V with a 200 kAIC interrupting rating at 600VAC. Beyond those electrical ratings, the application should accommodate the JKS-250's single-element construction, bolted blade-end-to-bolted blade-end connection, non-indicating configuration, and 7.13 x 2 x 2-inch dimensions.
