FRS-R-40 - 40Amp Fuse

FRS-R-40 - 40Amp Fuse

Finding the right 40-amp fuse means considering more than just the amperage. The FRS-R-40 uses ferrule connections on both ends and has a non-indicating design, so it does not include a built-in fuse-status indicator. Measuring 5.5 inches long by 1.84 inches high by 1.84 inches wide, this fuse provides technicians with specific dimensions to compare against existing component or equipment documentation. If you're replacing an FRS-R-40, confirm the full electrical rating, Class RK5 designation, connection type, and dimensions rather than relying on the 40A marking alone.

Key Features and Benefits

• 40A Class RK5 rating: Provides a specific amperage and fuse-class combination for matching compatible equipment requirements.
• 600 VAC voltage rating: Clearly defined AC rating makes specification comparisons straightforward.
• 250 VDC voltage rating: Provides a separate DC rating for equipment requiring compatible DC fuse specifications.
• Dual-element design: Matches the manufacturer's stated configuration for the FRS-R-40.
• 10-second response at 500%: Gives technicians a defined response-time specification to compare with equipment requirements.
• Ferrule end connections: Uses a ferrule end x ferrule end configuration for straightforward physical identification.
• Non-indicating: The fuse lacks an integrated status indicator.
• CE Marked: CE marking is included in the supplied manufacturer compliance information.
