FRS-R-250 - 250Amp Fuse

FRS-R-250 - 250Amp Fuse

For equipment that calls for an FRS-R-250 fuse, getting the full specification right matters just as much as matching the 250-amp rating. The Eaton Bussmann FRS-R-250 is a 250A Class RK5 dual-element fuse rated for 600 VAC and 300 VDC. Physical size is another detail worth checking: the FRS-R-250 measures 11.63 inches long, 2.59 inches high, and 2.59 inches wide. Whether you're matching an existing FRS-R-250 or comparing specifications from equipment documentation, checking the fuse class, voltage ratings, interrupting capacity, connection style, and dimensions can help you identify the correct fit rather than relying on amperage alone.

Key Features and Benefits

• 250A Class RK5 rating: Provides a clearly defined amperage and fuse class for matching against equipment requirements.
• 600 VAC and 300 VDC ratings: Gives you specified voltage ratings for compatible AC and DC equipment.
• Dual-element design: Matches the manufacturer's specified element configuration for the FRS-R-250.
• Specified response characteristic: Rated at 10 seconds at 500% of rated current, giving technicians another important specification to compare.
• Blade connections on both ends: Makes the physical connection configuration straightforward to identify during replacement work.
• Non-indicating configuration: Designed without a built-in fuse-status indicator.
