    • 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.
    • 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.
    • Current-limiting design reduces damage to equipment caused by heating and magnetic effects of short-circuit currents.
    • 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.
    • 200,000 A.I.R. rating minimizes need for short circuit calculations.
    • Refer to FLNR for KLNR dimensions and FLSR for KLSR dimensions.
