JJS-70 - 70Amp Fuse

JJS-70 - 70Amp Fuse

When you’re identifying a replacement fuse, a few exact details can save a lot of uncertainty later. The Eaton Bussmann series JJS-70 is a 70A, 600V Class T fuse with a manufacturer-specified interrupting rating of 200 kAIC at 600VAC. Whether you’re replacing an existing JJS-70 or verifying a fuse for compatible equipment, the important thing is to match the complete specification—not simply the 70-amp rating. With clearly defined ratings and dimensions, this Class T fuse is built to last while giving maintenance professionals the concrete information they need to make an informed component selection.

Key Features and Benefits

• 70A amperage rating: Designed for equipment requiring a 70-amp Class T fuse.
• 600V rating: Provides a clearly defined voltage specification for compatibility checks.
• Class T fuse: Makes the fuse class easy to identify when reviewing equipment documentation or an existing component.
• Bolted blade connections: Uses a bolted blade end x bolted blade end configuration that can be checked against the equipment’s required connection arrangement.
• Non-indicating design: Does not incorporate a built-in visual fuse-status indicator.

Where It Works Best

The JJS-70 70A 600V Class T fuse is best considered for compatible existing electrical equipment that specifically calls for its combination of 70A amperage, 600V rating, Class T configuration, 200 kAIC interrupting rating at 600VAC, and bolted blade connections. Its 2.95 x 0.75 x 0.75-inch dimensions should also meet the equipment's physical requirements.
