FLNR/FLSR Class RK5 Fuses

250/600 VAC

Littelfuse FLNR/FLSR series fuses have been the superior

UL Class RK5 dual-element time-delay fuses, and are the

most widely used class of fuses. FLNR/FLSR series fuses

provide excellent protection for all types of circuits especially

those containing motors. However, users and specifiers

should consider the significant benefits offered by Indicator

fuses. Complete information on these fuses may be found in

this section of this catalog.

APPLICATIONS

Service entrance switches

Switchboard main and feeder switches

Motor control center mains and motor branch circuits

Individual fused combination motor controllers

Distribution panelboards

Industrial control panels

Protection of fully-rated panelboards and loadcenters

All general purpose circuits

SAFETY

RELIABILITY

200,000 A.I.R. — Reliable interruption of all overcurrents

up to 200,000 amperes.

Faster acting short circuit protection than any non-current

limiting mechanical protective device.

Accurate and reliable — Automated, precision manufac-

tured and assembled parts ensure accurate, consistent

response to overloads and short circuits.

Dual-Element, Time-Delay

1/10 – 600 Amperes

SPECIFICATIONS

Voltage Ratings:

Interrupting Ratings: AC: 200,000 amperes rms symmetrical

Ampere Range: 1/10 – 600 amperes

Approvals: Standard 248-12, Class RK5

AMPERE RATINGS

**FLNR only, *FLSR only

Example part number (series & amperage): FLSR100

RECOMMENDED FUSE BLOCKS

Refer to Fuse Block section of this catalog for additional

information.

DIMENSIONS

Refer to FLNR_ID series for FLNR dimensions and

FLSR_ID series for FLSR dimensions.
