FRN-R-12 - 12 Amp Fuse

FRN-R-12 - 12 Amp Fuse

The FRN-R-12 is a 12A Class RK5 dual-element fuse for electrical applications requiring a precise combination of amperage, voltage, interrupting capacity, and physical fit. Rated for 250V AC and 125V DC, it carries an interrupting rating of 200 kAIC at 250V AC and 20 kAIC at 125V DC. Its dual-element construction is paired with a manufacturer-specified 8-second response time at 500% of rated current, an important characteristic to compare when you're replacing a fuse or checking it against equipment requirements.

Key Features and Benefits

• 12A Class RK5 fuse – A clearly defined current rating and fuse class make replacement identification more straightforward.
• Dual-element construction – Matches equipment specifications that specifically require a dual-element fuse.
• 250V AC / 125V DC rating – Provides published ratings for compatible AC and DC applications.
• 8-second response at 500% – Manufacturer-specified response information helps you compare the fuse's operating characteristics with application requirements.
• Ferrule end × ferrule end connection – An important physical detail when confirming compatibility with the existing fuse arrangement.
• Compact 2-inch length – Useful when checking the available space and physical fit before installation.

Material Compliance and Certifications

The supplied manufacturer specifications identify the FRN-R-12 as CE-marked. That's the catalog-specific compliance information provided for this product.

If an installation, project specification, or facility standard requires additional certifications or material-compliance documentation, verify those requirements for the exact FRN-R-12 catalog number. This is preferable to assuming that certifications associated with another fuse in the same product family automatically apply to this model.

Where It Works Best

• Exact FRN-R-12 replacement applications – A practical choice when the existing equipment specification calls for this catalog number and its published ratings.
• 12A Class RK5 fuse applications – Suited to equipment requiring the specific combination of a 12A rating and Class RK5 classification.
• 250V AC circuits – For properly specified AC applications operating within the fuse's ratings, including the required interrupting capacity.
• 125V DC circuits – Can also be used in compatible DC applications within its 125V DC and 20 kAIC ratings.
• Dual-element fuse requirements – Appropriate when dual-element construction and the stated response characteristics match the equipment specification.
