JKS-20 - 20 Amp Fuse

JKS-20 - 20 Amp Fuse

A fuse replacement gets much easier to evaluate when the label, electrical ratings, connection style, and physical size all tell the same story. The Eaton Bussmann series JKS-20 is a 20A, 600V Class J fuse rated by the manufacturer for 200 kAIC at 600VAC. When your equipment requires these characteristics, the JKS-20 offers a straightforward way to match the required form, fit, and electrical ratings without guesswork. It’s built to last, but as with any electrical component, correct selection begins with confirming every relevant specification against the equipment requirements.

Key Features and Benefits

• 20A amperage rating: Clearly specified for equipment requiring a 20-amp Class J fuse.
• 600V rating: Provides a defined voltage specification for compatibility checks.
• Class J configuration: Makes the fuse class easy to identify when comparing the JKS-20 with equipment documentation or an existing fuse.
• Ferrule connections: Uses ferrule end x ferrule end connections, an important physical detail when confirming fit.
• Single element: The JKS-20 is specified with one element.
• Non-indicating: Designed without a visual fuse-status indicator.

Where It Works Best

The JKS-20 20A 600V Class J fuse is best suited to compatible electrical equipment that specifically calls for a 20A Class J fuse with a 600V rating, 200 kAIC interrupting rating at 600VAC, single-element configuration, ferrule-to-ferrule connections, and a non-indicating design. Also check its 2.25 x 0.81 x 0.81-inch dimensions against the intended equipment.
