FLNR050-ID - 50Amp Fuse

FLNR050-ID - 50Amp Fuse

The FLNR050-ID is a 50-amp, 250 VAC Class R time-delay fuse designed for your applications where temporary current surges are expected but reliable overcurrent protection remains essential. Its time-delay operation allows the fuse to handle normal, short-lived inrush currents without opening unnecessarily. When a genuine overload or fault occurs, its current-limiting design provides the protection the circuit requires. The FLNR050-ID also has an indicating feature that can make troubleshooting a little easier by helping maintenance personnel quickly identify an open fuse.

Where It Works Best

The FLNR050-ID 50-amp fuse makes sense in compatible electrical systems where equipment can draw additional current for a short period during startup. That's where the time-delay characteristic becomes particularly useful.

For replacement applications, the important thing is to match the electrical requirements—not just the 50-amp rating. Check the 250 VAC voltage rating, Class R configuration, time-delay characteristic, 200 kA interrupting rating, current-limiting design, and physical dimensions against the requirements of the equipment and existing fuse.
