FRS-R-70 - 70Amp Fuse

FRS-R-70 - 70Amp Fuse

Matching a replacement FRS-R-70 fuse takes more than finding another fuse marked 70 amps. Unlike ferrule-ended configurations, this model uses blade connections at both ends, so the connection style is an important detail to verify. The FRS-R-70 is also non-indicating, meaning it lacks a built-in fuse-status indicator. Physically, it measures 7.88 inches long, 1.34 inches high, and 1.34 inches wide, and weighs 0.35 lb. Whether you're checking an existing FRS-R-70 or working from equipment documentation, comparing the complete specification—amperage, voltage, fuse class, interrupt rating, blade configuration, and dimensions—helps you make a more informed decision about compatibility.

Key Features and Benefits

• 70A Class RK5 fuse: Provides a clearly defined amperage and fuse-class combination for matching against equipment specifications.
• Dual-element configuration: Matches equipment specifications that specifically call for a dual-element Class RK5 fuse.
• Specified response characteristic: Manufacturer data lists a response time of 10 seconds at 500% of rated current.
• Blade connections: Feature a blade-end-to-blade-end configuration, giving technicians a clear physical characteristic to check during replacement.
• Non-indicating design: The fuse lacks a built-in status indicator, so this characteristic cannot be confirmed before installation.
• CE Marked: CE marking is identified in the supplied manufacturer specifications.

Where It Works Best

The FRS-R-70 70A fuse makes sense for compatible electrical equipment whose documentation specifically calls for a Class RK5 dual-element fuse with blade-end connections and electrical ratings matching this model. Its combination of 70A, 600 VAC, and 300 VDC ratings, together with the applicable interrupt ratings, gives maintenance teams and technicians concrete values to compare with the equipment requirements.
