General Purpose Fuses

KLNR/KLSR Class RK1 Fuses

250/600 VAC • Fast Acting • 1 – 600 Amperes

Applications

Resistance heaters

Lighting circuits

Non-inductive loads

Molded case circuit breaker load centers and panelboards have

increased interrupting ratings when series rated with Littelfuse

KLNR/KLSR Class RK1 fuses. Refer to panelboard manufacturer’s

literature for UL Listed combination of fuses and panelboards. Series

ratings up to 200,000 amperes are available.

Safety

•

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

200,000 amperes.

Extremely current-limiting — Stops damaging short-circuit current

faster than any mechanical protective device.

Fast-acting — Provides fast acting protection to equipment such

as variable speed drives, rectifiers and other equipment containing

surge-sensitive components.

Longer Equipment Life

•

Current-limiting design reduces damage to equipment caused by

heating and magnetic effects of short-circuit currents.

Economical

•

Extremely current-limiting — often permits use of readily available,

less costly equipment.

Used as input or output fuses for surge sensitive components such

as variable speed drives and rectifiers, fast acting KLNR/KLSR fuses

may prevent opening of expensive semiconductor fuses protecting

individual components.

KLNR/KLSR series RK1 fuses were the earliest type of current-limiting

fuses developed. Their single-element, silver link design enables them

to provide fast-acting overload and short-circuit protection. When used

to protect inductive loads such as motors, solenoids, and transformers,

KLNR/KLSR series fuses must be greatly oversized to prevent opening

the fuses on harmless in-rush currents. In such applications, KLNR/

KLSR series fuses may only provide short-circuit protection.

•

Easy To Use

We recommend using POWR-PRO^®LLNRK/LLSRK series Class RK1,

dual-element, time-delay fuses in all new applications requiring the

current-limiting ability of UL Class RK1 fuses. POWR-PRO LLNRK/

LLSRK series fuses are also recommended in existing applications

where fast-acting RK1 or RK5 fuses have been opening on harmless

system surges such as motor starting currents.

200,000 A.I.R. rating minimizes need for short-circuit calculations.

Dimensions

•

Refer to FLNR_ID for KLNR dimensions and FLSR_ID for KLSR

dimensions.
