JJS-800 - 800Amp Fuse

JJS-800 - 800Amp Fuse

When you're checking fuses, you need to know the amperage, voltage, class, and connection style. The Eaton Bussmann series JJS-800, for example, has an 800A rating and 600V capacity with a Class T configuration, plus a 200 kAIC interrupting rating at 600VAC.

Key Features and Benefits

• 800A amperage: Provides a clearly defined current rating for applications specified for an 800-amp fuse.
• 600V rating: Designed around the manufacturer's stated 600-volt electrical rating.
• Class T configuration: Clearly identified as a manufacturer's T fuse, making fuse-class verification straightforward.
• Bolted blade connections: Features bolted blade-to-bolted blade construction, an important physical detail when checking compatibility.
• Non-indicating design: This model does not incorporate a visual fuse-status indicator.

Where It Works Best

The JJS-800 800A Class T fuse is best suited to compatible electrical equipment specifically requiring its combination of 800A amperage, 600V rating, Class T configuration, 200 kAIC interrupting rating at 600VAC, bolted blade connections, and stated physical dimensions. Replacing an existing JJS-800 is particularly straightforward because you can check the catalog number, electrical ratings, connection arrangement, and dimensions against the equipment requirements.
