FRN-R-225 - 225Amp Fuse

FRN-R-225 - 225Amp Fuse

For a 225A Class RK5 fuse, the FRN-R-225 packs quite a bit of useful information into a compact 2-inch body. It is rated for 250V AC and 125V DC, uses a dual-element construction, and has blade connections at both ends. On AC circuits, its published interrupting rating is 200 kAIC at 250V AC; for DC applications, the rating is 20 kAIC at 125V DC. Eaton specifies a 10-second response time at 500% of rated current. The FRN-R-225 is also non-indicating, which matters when you're matching an existing fuse or working from an equipment specification.

Key Features and Benefits

• 225A Class RK5 fuse – Rated at 225 amps with the Class RK5 classification specified for this catalog number.
• Dual-element construction – Matches equipment requirements calling for a dual-element fuse.
• 250V AC / 125V DC – Suitable for compatible AC or DC circuits within these published voltage ratings.
• 10 seconds at 500% – Eaton's stated response-time specification gives you another important point to compare with the requirements of the application.
• Blade ends on both sides – Matches installations requiring a blade-to-blade fuse connection.
• Non-indicating configuration – The correct configuration when the installation specifies the non-indicating FRN-R-225.

Material Compliance and Certifications

The FRN-R-225 is CE-marked in accordance with the supplied manufacturer specifications.

No additional certification or material-compliance information was provided for this exact catalog number. If a job requires particular approvals or documentation, check those requirements against the FRN-R-225 specifically rather than relying on information for another fuse in the series.

Where It Works Best

• Replacing an existing FRN-R-225 where the catalog number and complete electrical specifications match.
• 225A Class RK5 installations requiring this amperage and fuse classification.
• Blade-style fuse connections that match its blade end × blade end construction.
• Dual-element applications where the manufacturer's stated 10-second response at 500% meets the equipment requirements.
• Electrical maintenance and repair work where matching the original fuse's class, ratings, response, connection style, and dimensions is essential.
