FRS-R-25 - 25Amp Fuse

FRS-R-25 - 25Amp Fuse

Getting the right replacement fuse means checking more than the amperage printed on the label. The Eaton Bussmann FRS-R-25 is a 25A Class RK5 dual-element fuse rated for 600 VAC and 300 VDC. It is also non-indicating, so there is no built-in fuse status indicator. If FRS-R-25 appears in your equipment documentation or on the fuse you're replacing, compare the complete specifications—not just the 25-amp rating—to ensure the electrical characteristics and physical configuration match your requirements.

Key Features and Benefits

• 25A Class RK5 rating: Clearly identifies the amperage and fuse class for comparison with equipment specifications.
• 600 VAC and 300 VDC voltage ratings: Provides defined ratings for compatible AC and DC applications.
• Dual-element construction: Matches the specified configuration of the FRS-R-25.
• 10-second response at 500%: Supplies a clear manufacturer-defined response characteristic for specification matching.
• Ferrule ends on both sides: Makes the connection style easy to identify when comparing the fuse with an existing component.
• Non-indicating design: This model lacks a built-in fuse status indicator.

Where It Works Best

The FRS-R-25 25A fuse is suited to compatible electrical equipment that specifically calls for a Class RK5 dual-element fuse with ferrule end connections and matching electrical ratings. With its 600 VAC and 300 VDC voltage ratings, plus separately stated AC and DC interrupt ratings, the specifications provide maintenance teams and electricians several concrete points to verify against the equipment documentation.
