JKS-350 - 350 Amp Fuse

JKS-350 - 350 Amp Fuse

When your equipment calls for a 350-amp Class J fuse, the useful details are the ones you can verify before the part ever reaches the installation point. The Eaton Bussmann series JKS-350 is a 350A, 600V Class J fuse with a manufacturer-specified 200 kAIC interrupting rating at 600VAC. Straightforward specifications matter with electrical components, and the JKS-350 provides clearly defined ratings and dimensions instead of vague marketing claims. It's built to last, but proper selection still comes down to confirming the complete electrical and physical specifications against the equipment's requirements.

Key Features and Benefits

• 350A amperage rating: Clearly identifies the fuse for equipment requiring a 350-amp Class J configuration.
• 600V rating: Manufacturer-rated at 600 volts.
• Class J fuse: The specified fuse class helps narrow compatibility beyond amperage and voltage alone.
• Single-element construction: Manufacturer specifications list one element for the JKS-350.
• Non-indicating design: This model does not incorporate a visual fuse-status indicator.

Where It Works Best

The JKS-350 350A 600V Class J fuse is best suited to compatible electrical equipment that specifically requires a 350A Class J fuse with a 600V rating and a 200 kAIC interrupting rating at 600VAC. Its bolted blade-end connections and 7.13 x 2 x 2-inch dimensions make physical configuration especially important when evaluating a replacement. The single-element, non-indicating characteristics should also match the equipment requirements.
