JJS-450 - 450Amp Fuse

JJS-450 - 450Amp Fuse

When you’re replacing a fuse in existing electrical equipment, the name on the label is only part of the story. The Eaton Bussmann series JJS-450 gives you a clearly defined set of electrical and physical specifications to check before installation: 450A, 600V, Class T, and a manufacturer-specified 200 kAIC interrupting rating at 600VAC. For maintenance teams, electricians, and facility personnel working with equipment that requires these characteristics, the JJS-450 puts the important numbers front and center. It’s built to last, but proper selection still depends on confirming that its ratings, connection style, dimensions, and fuse class match the equipment's requirements.

Key Features and Benefits

• 450A amperage rating: Provides the specified 450-amp rating for compatible equipment designed for this fuse size and class.
• 600V Class T configuration: Combines a 600V voltage rating with the manufacturer-specified Class T designation.
• Bolted blade connections: Features a bolted blade-to-bolted blade configuration, making connection style another straightforward compatibility checkpoint.
• Non-indicating design: This model does not include an integral visual indication of fuse status.

Where It Works Best

The JJS-450 450A Class T fuse suits compatible electrical equipment that requires a 450A, 600V fuse with a 200 kAIC interrupting rating at 600VAC. The application should also accommodate its bolted blade-to-bolted blade connection and 3.98 x 1.25 x 1.25-inch dimensions.
