JJN-70 - 70Amp Fuse

JJN-70 - 70Amp Fuse

If you already have JJN-70 on your maintenance list, the key question is whether every other detail matches the equipment. The Eaton Bussmann series JJN-70 is a 70A Class T fuse rated for 300VAC and 160VDC. The JJN-70 is non-indicating, so there is no built-in visual indicator for fuse status. It's built to last, and its clearly documented ratings give electricians, maintenance personnel, and equipment owners the practical information they need to compare the fuse with the requirements of an existing application. Rather than relying on appearance alone, you can check the catalog number, fuse class, amperage, AC or DC rating, interrupting capacity, connection style, and dimensions before deciding whether it is the correct fit.

Key Features and Benefits

• 70A Class T fuse with clearly identified electrical ratings for accurate component matching.
• Rated for 300VAC and 160VDC, allowing the applicable voltage rating to be checked against equipment requirements.
• Bolted blade-end x bolted blade-end connection provides a clearly defined physical connection configuration.
• Non-indicating configuration means the fuse does not include a built-in visual status indicator.
• Identified by catalog number JJN-70, helping maintenance teams distinguish the exact fuse model required.

Material Compliance and Certifications

Manufacturer specifications identify the JJN-70 as CE-marked and RoHS-compliant. These documented compliance details can be compared with the requirements of the equipment, facility, or project where the fuse will be used.

Where It Works Best

The Eaton Bussmann JJN-70 70A Class T fuse is best considered for compatible electrical equipment that specifically calls for its combination of 70A current rating, Class T configuration, 300VAC or 160VDC voltage rating, corresponding interrupting rating, bolted-blade connection, and 2.16 x 0.75 x 0.75-inch dimensions. It's particularly easy to evaluate when JJN-70 is already identified in equipment documentation or when the existing component provides enough information to compare each specification individually.
