FLNR100 - 100 Amp Fuse

FLNR100 - 100 Amp Fuse

When your application calls for a 100-amp Class RK5 time-delay fuse, the FLNR100 delivers the electrical characteristics needed for demanding commercial and industrial circuits. This dual-element fuse is rated for 250 VAC and 125 VDC. It uses a time-delay, or Slo-Blo, design that allows it to ride through normal short-duration current surges rather than opening unnecessarily. That's particularly helpful around motors, transformers, and other equipment that can draw considerably more current for a brief period during startup.

Key Features and Benefits

• 100A continuous current rating for properly matched electrical circuits.
• Class RK5, dual-element construction combines time-delay performance with overcurrent protection.
• Rated for applications up to 250VAC or 125VDC.
• Time-delay operation helps the fuse handle normal startup and inrush currents without unnecessary opening.
• Knife-blade configuration fits compatible fuse blocks, clips, and holders.
• A good fit for equipment where brief current surges are part of normal operation.
• Compatible with the LFR25100 Series holder.
• Non-indicating design with no visual blown-fuse indicator.

Material Compliance and Certifications

The information supplied for the FLNR100 identifies its Class RK5 construction and electrical performance specifications. Still, it does not provide enough product-specific information to confidently state individual RoHS, REACH, lead-free, or other material-compliance certifications. If one of these certifications is required for your facility or project, confirm the applicable documentation for the exact FLNR100 catalog number before installation.

Where It Works Best

The FLNR100 makes sense in commercial and industrial electrical systems where equipment may experience a temporary current spike during normal startup. Motors, transformers, machinery, and other inductive loads are common examples. Instead of reacting immediately to every brief surge, the fuse's time-delay characteristics allow normal inrush current to pass while still protecting against sustained overloads and fault conditions.
