FRN-R-175 - 175Amp Fuse

FRN-R-175 - 175Amp Fuse

The FRN-R-175 packs a very specific set of electrical characteristics into a compact 2-inch fuse. It's a 175A Class RK5 dual-element fuse rated for 250V AC and 125V DC, with blade connections on both ends and a non-indicating configuration. That combination of ratings matters during replacement work because current rating, voltage, fuse class, interrupting capacity, response characteristics, connection style, and physical dimensions all play a role in determining compatibility. If your equipment calls for the FRN-R-175, these are the details you'll want to verify before installation.

Key Features and Benefits

• 175A Class RK5 fuse – Gives you the specific amperage and fuse-class combination associated with the FRN-R-175.
• Dual-element construction – Matches equipment specifications that call for a dual-element fuse.
• Rated 250V AC and 125V DC – Suitable for compatible AC or DC applications within the manufacturer's published ratings.
• 10-second response at 500% – Gives electricians and technicians specific response information to compare with application requirements.
• Blade end × blade end connection – Easy to identify when checking the physical configuration of an existing fuse.
• Non-indicating configuration – Important when the equipment or replacement specification calls specifically for the non-indicating version.

Material Compliance and Certifications

The supplied specifications list the FRN-R-175 as CE Marked. That's the compliance information provided specifically for this catalog number.

For projects with additional certification or material-compliance requirements, check those requirements against documentation for the exact FRN-R-175 rather than assuming that information from another FRN-R fuse automatically applies.

Where It Works Best

• Exact FRN-R-175 replacements – Especially useful when servicing equipment that specifies this catalog number and its associated electrical characteristics.
• 175A Class RK5 applications – For installations requiring the combination of a 175A current rating and Class RK5 fuse.
• 125V DC applications – An option for compatible DC circuits within the fuse's 125V DC and 20 kAIC ratings.
• Dual-element fuse applications – Fits equipment specifications requiring dual-element construction and the stated response characteristic.
• Blade-style fuse installations – Useful where the existing setup requires blade connections on both ends.
