JKS-90 - 90 Amp Fuse

JKS-90 - 90 Amp Fuse

The Eaton Bussmann series JKS-90 makes the compatibility check refreshingly specific. You’re looking at a 90A, 600V Class J fuse with a manufacturer-specified 200 kAIC interrupting rating at 600VAC, one element, and bolted blade end x bolted blade end connections.

Key Features and Benefits

• 90A current rating: Designed for equipment requiring a 90-amp Class J fuse.
• 600V rating: Provides a clearly defined voltage specification for compatibility checks.
• Class J fuse: The clearly identified fuse class helps narrow the replacement search and avoids relying on appearance alone.
• Single element: Manufacturer specifications identify the JKS-90 as a one-element fuse.
• Non-indicating design: Both the fuse-indicator and special-feature fields identify this model as non-indicating.

Material Compliance and Certifications

The supplied manufacturer specifications identify the JKS-90 as CE-marked. The supplied information did not include RoHS, UL, CSA, REACH, or other compliance designations, so do not assume those certifications. If the application requires a particular approval, confirm the markings on the fuse and the applicable manufacturer documentation.

Where It Works Best

The Eaton Bussmann JKS-90 90A fuse is a practical choice for compatible existing electrical equipment specifically requiring a 90A, 600V Class J fuse with a 200 kAIC interrupting rating at 600VAC. Its bolted blade connections and defined dimensions are particularly important when checking physical fit. At the same time, the catalog number and electrical ratings help confirm that you’re looking at the intended component rather than a merely similar fuse.
