FRN-R-20 - 20 Amp Fuse

FRN-R-20 - 20 Amp Fuse

The FRN-R-20 is a reliable 20A Class RK5 fuse featuring dual-element construction and ferrule connections. It supports your 250V AC and 125V DC, with an interrupting rating of 200 kAIC at 250V AC and 20 kAIC at 125V DC. Notably, it has an 8-second response time at 500% of its rated current, making it easy to compare with specifications in equipment documentation during maintenance work.

Key Features and Benefits

• 20A Class RK5 rating – The combination to look for when equipment documentation specifies a 20-amp Class RK5 fuse.
• 250V AC / 125V DC – Published voltage ratings for compatible AC and DC circuits.
• Dual-element construction – A key part of the FRN-R-20's operating characteristics and an important detail when comparing replacement fuses.
• 8 seconds at 500% response time – Manufacturer-specified response data that can be checked against the requirements of the equipment.
• Ferrule ends – Ferrule-to-ferrule connections provide a specific physical configuration for matching the existing installation.
• Non-indicating – Worth confirming when replacing a fuse in equipment that calls for this configuration.

Material Compliance and Certifications

The supplied specifications list the FRN-R-20 as CE-marked. No additional certifications or material compliance declarations were included in the provided product information.

If a particular certification or environmental compliance standard is required for the installation, confirm it for the exact FRN-R-20 rather than assuming that information for another FRN-R fuse applies to this catalog number.

Where It Works Best

• Direct FRN-R-20 replacement work where the equipment documentation specifies this catalog number
• 20A Class RK5 requirements that match the fuse's published characteristics
• 250V AC circuits requiring a fuse rated at 200 kAIC at 250V AC
• 125V DC circuits compatible with the 20 kAIC at 125V DC rating
• Ferrule-style fuse holders that match its ferrule-end configuration and physical dimensions
• Maintenance and repair work where the fuse class, response characteristic, voltage ratings, interrupting capacity, and physical fit all need to match
