FRS-R-3 - 3Amp Fuse

FRS-R-3 - 3Amp Fuse

Matching a replacement fuse is easier when you have more than the amperage printed on the label. The FRS-R-3 uses ferrule connections on both ends, measures 5 inches long by 0.81 inches high by 0.81 inches wide, and weighs 0.14 lb. It is also non-indicating, so there is no built-in fuse-status indicator. If you're replacing an existing FRS-R-3 fuse, the catalog number and 3A rating are useful starting points, but they aren't the only details to check.

Key Features and Benefits

• 3A Class RK5 rating: Provides technicians with a specific amperage and fuse class for comparison with equipment documentation.
• 600 VAC / 300 VDC voltage ratings: Clearly defines the manufacturer's specified AC and DC voltage ratings for compatible equipment.
• Dual-element configuration: Matches the manufacturer's specified design for the FRS-R-3.
• Defined response characteristic: The manufacturer specifies a response time of 10 seconds at 500% of rated current.
• Ferrule end x ferrule end connection: Makes the connection configuration easy to identify when comparing a replacement fuse.
• Non-indicating design: Does not incorporate a built-in fuse-status indicator.
• Clearly documented size: At 5 x 0.81 x 0.81 inches, the published dimensions provide useful reference points for checking physical compatibility.

Where It Works Best

The FRS-R-3 3A fuse is best suited for compatible electrical equipment that specifically requires a 3A Class RK5 dual-element fuse with ferrule-end connections and matching voltage and interrupting characteristics. Its 600 VAC and 300 VDC ratings, together with separate published AC and DC interrupt ratings, provide clear reference points when comparing the fuse with equipment documentation or an existing component.
