FRS-R-8 - 8Amp Fuse

FRS-R-8 - 8Amp Fuse

When you’re replacing an FRS-R-8 fuse, matching the 8-amp rating is only the beginning. The Eaton Bussmann FRS-R-8 is a dual-element Class RK5 fuse rated at 8A, 600 VAC, and 300 VDC. Its published interrupt ratings are 200 kAIC at 600 VAC and 20 kAIC at 300 VDC, with a manufacturer-specified response time of 10 seconds at 500% of rated current. This model uses ferrule connections on both ends, an important physical detail when you’re checking an existing fuse or comparing specifications from equipment documentation. It’s also non-indicating, so there is no built-in fuse-status indicator.

Key Features and Benefits

• 8A Class RK5 rating: Clearly identifies the amperage and fuse class for straightforward comparison with equipment requirements.
• Dual-element configuration: Matches specifications that specifically require a dual-element Class RK5 fuse.
• Defined response characteristic: Manufacturer specifications list a response time of 10 seconds at 500% of rated current.
• Ferrule ends: Uses a ferrule end x ferrule end connection, providing an easy-to-check physical characteristic when identifying a replacement.
• Non-indicating design: Does not include a built-in fuse-status indicator.
• CE Marked: The supplied manufacturer specifications indicate that the FRS-R-8 is CE Marked.
