JJS-350 - 350Amp Fuse

JJS-350 - 350Amp Fuse

When you're replacing a fuse in existing electrical equipment, there's little value in guesswork—the catalog number, electrical ratings, connection style, and physical size must match the application. The Eaton Bussmann series JJS-350 is a 350A, 600V Class T fuse with a manufacturer-specified 200 kAIC interrupting rating at 600VAC. For maintenance teams, electricians, and facility personnel looking for the exact JJS-350 configuration, these clearly documented specifications make it easier to confirm whether the fuse fits the intended application. It's built to last, with the focus where it should be: the correct electrical and physical match.

Key Features and Benefits

• 350A amperage rating: Designed for compatible equipment specifically requiring a 350-amp Class T fuse.
• 600V rating: Provides a clear voltage specification to check against the electrical system's requirements.
• Class T configuration: Clearly identified as a Class T fuse, helping narrow down the correct replacement when servicing equipment built around this fuse class.
• Bolted blade connections: Uses a bolted blade-to-bolted blade configuration, giving installers a specific connection style to confirm before installation.
• Non-indicating design: The JJS-350 does not incorporate a visual fuse-status indicator.

Where It Works Best

The Eaton Bussmann JJS-350 is best suited to compatible electrical equipment that specifically calls for a 350A, 600V Class T fuse with a 200 kAIC interrupting rating at 600VAC. Its bolted blade-to-bolted blade-end connection and 3.63 x 1 x 1-inch dimensions are equally important in determining whether it physically matches the intended equipment.
