JJN-175 - 175Amp Fuse

JJN-175 - 175 Amp Fuse

When you're checking a replacement fuse, the amperage on the label is only part of the story. The Eaton Bussmann JJN-175 is a 175-amp Class T fuse rated for 300VAC and 160VDC, giving you clear electrical and physical details to compare with your equipment. The JJN-175 is also non-indicating, so it does not provide a visual indication of fuse status. With documented ratings, a compact Class T format, and straightforward compatibility points, it's built to last and gives maintenance professionals the information they need to evaluate the fuse for the job without guesswork.

Key Features and Benefits

• 175A Class T fuse: Designed for equipment requiring a 175-amp Class T fuse configuration.
• AC and DC voltage ratings: Rated for 300VAC and 160VDC, so you can match the appropriate rating to the application.
• Bolted blade connections: Uses a bolted blade-to-bolted blade configuration, an important detail when matching an existing fuse.
• Non-indicating design: This model does not include a visual fuse-status indicator.

Material Compliance and Certifications

According to the supplied manufacturer specifications, the JJN-175 is CE Marked and RoHS Compliant.

No UL, CSA, REACH, or other certification information was provided for this specific catalog number. Do not assume those approvals simply because another fuse in the same product family may carry them. Where a particular certification is required, verify the markings on the fuse and the applicable manufacturer documentation.

Where It Works Best

The JJN-175 is best evaluated for existing electrical equipment that specifically requires a 175A Class T fuse with the corresponding voltage, interrupting, physical, and connection requirements. For AC equipment, compare the application with the fuse's 300VAC rating and 200 kAIC interrupting rating. For DC equipment, the relevant manufacturer ratings are 160VDC and 20 kAIC.

A matching JJN-175 catalog number is a useful starting point, but it isn't the entire compatibility check. Confirm the amperage, Class T designation, applicable AC or DC voltage and interrupting rating, dimensions, connection style, and equipment requirements before installation. Similar-looking fuses are not necessarily interchangeable. If suitability is uncertain, have a qualified electrical professional verify the application.
