FLNR045-ID - 45Amp Fuse

FLNR045-ID - 45Amp Fuse

When you need a 45 amp Class R fuse with time-delay protection and a high interrupting rating, the FLNR045-ID is built for the job. This cartridge-style fuse is rated for 250 VAC. It has a 200 kA interrupting rating at 250 VAC, making it suitable for compatible electrical systems where high available fault current is a concern. Its time-delay design allows brief, normal current surges to occur without immediately opening the circuit—an important advantage for equipment that experiences startup or inrush current.

Key Features and Benefits

• 45 amp rating for compatible electrical circuits and equipment
• Rated for operation up to 250 VAC
• Time-delay protection accommodates temporary startup and inrush currents
• Current-limiting Class R design helps limit fault-current energy
• Indicating design can make fuse-status checks and troubleshooting more convenient
• Compact cartridge-style construction
• Suitable for replacement applications requiring the FLNR045-ID specifications

Where It Works Best

The FLNR045-ID is a good fit for compatible commercial and industrial electrical applications that call for a 45A, 250V Class R time-delay fuse. Because it can tolerate temporary inrush currents, it's especially useful in circuits where equipment may draw more current for a short period during startup.

The indicating feature is handy in maintenance environments, too. When you're tracking down an electrical issue, being able to check fuse status more easily can save time. And with its 200 kA interrupting rating, the FLNR045-ID offers the high fault-current capability required by appropriately rated applications.
