FRS-R-9 - 9Amp Fuse

FRS-R-9 - 9Amp Fuse

When you’re replacing an FRS-R-9 fuse, matching the 9-amp rating is a good start—but there’s more to check before calling it a match. The Eaton Bussmann FRS-R-9 is a 9A Class RK5 fuse with a dual-element configuration and voltage ratings of 600 VAC and 300 VDC. According to the manufacturer's specifications, its interrupt rating is 200 kAIC at 600 VAC and 20 kAIC at 300 VDC, with a specified response time of 10 seconds at 500% of rated current.

Key Features and Benefits

• 9A Class RK5 rating: Clearly defined amperage and fuse class make it easier to compare the FRS-R-9 with equipment requirements.
• Dual-element configuration: Built with the dual-element design specified for this catalog number.
• Defined response characteristic: Manufacturer specifications list a response time of 10 seconds at 500% of rated current.
• Ferrule connections: Uses ferrule ends on both sides, an important physical detail when checking replacement compatibility.
