FLNR090 - 90 Amp Fuse

FLNR090 - 90 Amp Fuse

The FLNR090 is a 90A Class RK5 dual-element time-delay fuse for your electrical systems that experience both normal startup surges and serious fault conditions. It is rated for 250VAC and 125VDC and uses a knife-blade design for installation in a compatible fuse block, clip, or holder.

Key Features and Benefits

• 90A rating: For circuits specified for a 90-amp fuse.
• Class RK5 design: Provides current-limiting overcurrent protection for compatible applications.
• Time-delay operation: Helps handle brief inrush currents without opening unnecessarily.
• Dual-element construction: Protects against both overloads and short circuits.
• Voltage ratings: Suitable for circuits up to 250 VAC or 125 VDC.
• High interrupting rating: Up to 300 kA AC and 20 kA DC, depending on the circuit and operating voltage.
• Knife-blade construction: Fits compatible fuse blocks, clips, and holders.
• Non-indicating type: Does not include a blown-fuse indicator.
• Industrial use: Suitable for many commercial and industrial overcurrent protection applications.

Material Compliance and Certifications

Manufacturer documentation for the FLNR series lists UL and CSA approvals, including the FLNR090. If your project has specific requirements for RoHS, REACH, lead-free materials, or other environmental standards, confirm the exact fuse meets those requirements before ordering or installing.

Where It Works Best

The FLNR090 90A Class RK5 fuse works well in commercial and industrial circuits where equipment draws extra current during startup. Common applications include motor circuits, transformers, solenoids, feeders, branch circuits, and control equipment.

Its time-delay response is useful for motor-driven equipment and other loads with short-term inrush current. However, the circuit must be designed for a 90A, 250VAC/125VDC Class RK5 fuse.
