FRS-R-500 - 500Amp Fuse

FRS-R-500 - 500Amp Fuse

Need to match an FRS-R-500 fuse? The 500-amp rating is important, but it's only one piece of the specification. This model uses blade connections at both ends and is non-indicating, so it lacks a built-in fuse-status indicator. It's also a sizable component, measuring 13.38 inches long by 3.13 inches high by 3.13 inches wide and weighing 3.6 lb. When you're comparing the FRS-R-500 with an existing fuse or equipment documentation, checking these details together—amperage, fuse class, voltage, interrupt rating, connection style, and dimensions—provides a much more useful compatibility check than simply matching the 500A marking.

Key Features and Benefits

• 500A Class RK5 fuse: Provides a clearly defined amperage and fuse class for matching against equipment specifications.
• Dual-element construction: Meets applications and equipment specifications that require a dual-element Class RK5 fuse.
• Specified response characteristic: Manufacturer data lists a response time of 10 seconds at 500% of rated current.
• Blade end connections: Blade end x blade end configuration gives you another physical detail to verify when replacing an existing fuse.
• Non-indicating design: Does not incorporate a built-in fuse-status indicator.
• CE Marked: CE marking is included in the supplied manufacturer compliance information.

Where It Works Best

The FRS-R-500 is appropriate for compatible electrical equipment that requires a 500A Class RK5 dual-element fuse with blade-end connections and electrical specifications matching this model. Its ratings of 600 VAC and 300 VDC, along with the corresponding interrupt ratings of 200 kAIC at 600 VAC and 20 kAIC at 300 VDC, provide clear reference points for evaluating compatibility.
