FRS-R-80 - 80Amp Fuse

FRS-R-80 - 80Amp Fuse

Replacing an FRS-R-80 fuse? The 80-amp rating may be the first thing you notice, but a proper match involves several other specifications. The FRS-R-80 is also non-indicating, meaning there is no built-in fuse-status indicator. If you're matching an existing FRS-R-80 or checking equipment documentation, compare the complete specification—not simply the 80A marking—to determine whether this is the correct fuse for the equipment.

Key Features and Benefits

• 80A Class RK5 fuse: Combines an 80-amp rating with the specific Class RK5 designation for accurate replacement matching.
• Dual-element configuration: Provides the dual-element construction specified for the FRS-R-80.
• Defined response characteristic: Manufacturer data specifies a response time of 10 seconds at 500% of rated current.
• Blade-to-blade connection: Blade ends on both sides make the connection style straightforward to identify when comparing replacement specifications.
• Non-indicating design: The fuse lacks a built-in status indicator.
• CE Marked: Manufacturer specifications indicate that this catalog number is CE Marked.

Where It Works Best

The Eaton Bussmann FRS-R-80 80A fuse makes sense for compatible electrical equipment specifically requiring a dual-element Class RK5 fuse with the electrical ratings and blade connection configuration specified for the FRS-R-80. It can be evaluated against requirements calling for 80A, 600 VAC, or 300 VDC, provided the corresponding interrupt rating and all other equipment specifications also match.
