JKS-450 - 450 Amp Fuse

JKS-450 - 450 Amp Fuse

When your electrical system calls for a 450-amp Class J fuse, the useful question isn’t simply whether the amperage matches. Voltage, interrupting rating, connection style, physical size, and fuse class all belong on the checklist. For equipment requiring this exact combination of ratings and configuration, the JKS-450 offers clear specifications and is built to last. Still, proper suitability depends on matching the complete fuse specification to the equipment requirements.

Key Features and Benefits

• 450A amperage rating: Clearly identifies the current rating for compatibility checks with existing equipment.
• 600V rating: Designed around a manufacturer-specified 600V voltage rating.
• Class J fuse: Makes it easier to narrow the selection when equipment documentation specifically calls for Class J.
• Single element: Manufacturer specifications identify one fuse element.

Material Compliance and Certifications

The supplied manufacturer specifications identify the JKS-450 as RoHS Compliant. No CE, UL, CSA, REACH, or other certification/compliance designation was supplied for this exact catalog number, so do not assume those certifications.

Where It Works Best

The Eaton Bussmann JKS-450 is best suited for compatible electrical equipment that requires a 450A, 600V Class J fuse with a 200 kAIC interrupting rating at 600VAC. Its single-element construction, bolted blade-end x bolted blade-end connection, and 8 x 2.5 x 2.5-inch dimensions provide additional checkpoints when evaluating a replacement for existing equipment.
