FRS-R-7 - 7Amp Fuse

FRS-R-7 - 7Amp Fuse

When you're replacing an FRS-R-7 fuse, the 7-amp rating is only the beginning of the compatibility check. Those details matter when you're comparing a replacement. Rather than stopping once you've found another 7A fuse, check the class, voltage rating, interrupting rating, connection style, and physical dimensions against the equipment requirements. That makes the FRS-R-7 easier to identify accurately and gives technicians and maintenance professionals the information they need without having to sort through vague or unnecessary claims.

Key Features and Benefits

• 7A Class RK5 rating: Clearly identifies the amperage and fuse class for comparison with equipment specifications.
• Dual-element configuration: Matches applications and equipment specifications that specifically require this element configuration.
• 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, an important physical detail when checking replacement compatibility.
• Non-indicating design: There is no built-in fuse-status indicator, making the configuration clear before installation.
• CE Marked: CE marking is included in the supplied manufacturer specifications.

Where It Works Best

The Eaton Bussmann FRS-R-7 7A fuse is appropriate for compatible electrical equipment that calls for a Class RK5, dual-element fuse with ferrule connections and electrical ratings matching this catalog number. If FRS-R-7 already appears in the equipment documentation or on the fuse being replaced, that gives you a useful starting point for identifying the required component.
