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.
