FLNR110 - 110 Amp Fuse

FLNR110 - 110 Amp Fuse

When your circuit has to handle normal startup surges without sacrificing dependable overcurrent protection, the FLNR110 is built for the job. This 110-amp Class RK5 time-delay fuse features a dual-element design and is rated for 250 VAC and 125 VDC. Its Slo-Blo/time-delay operation allows the fuse to handle temporary inrush currents that can occur when equipment starts, rather than opening due to a brief, expected surge. At the same time, it provides the required protection when an overcurrent condition persists.

Key Features and Benefits

• 110A continuous current rating for applications requiring a 110-amp Class RK5 fuse.
• Time-delay operation helps the fuse tolerate brief startup and inrush currents.
• Dual-element design combines time-delay characteristics with overcurrent protection.
• Rated for circuits up to 250VAC and 125VDC.
• Knife-blade configuration fits compatible fuse blocks, clips, and holders.
• Designed as a Class RK5 fuse, making fuse-class matching easier when servicing existing equipment.
• Non-indicating construction for applications where a visual blown-fuse indicator isn't required.
• Compatible with the LFR25200 Series fuse holder.

Material Compliance and Certifications

The FLNR110 is a Class RK5 fuse. The product information provided does not specify individual environmental or material compliance declarations, such as RoHS, REACH, or lead-free status. If one of these certifications is required for your facility, project, or application, verify the applicable documentation for the FLNR110 before installation.

Where It Works Best

The FLNR110 makes the most sense in electrical applications where temporary current surges are part of normal operation. Motors, transformers, industrial machinery, and other inductive loads can draw considerably more current at startup than they do once they're running. A time-delay fuse is useful in these situations because it can accommodate a brief, expected surge while still protecting against sustained overcurrent conditions.

It's also a practical replacement choice for industrial equipment, electrical distribution systems, motor circuits, machinery, and equipment panels already designed around a 110A, 250VAC Class RK5 time-delay fuse with knife-blade construction.
