General Purpose Fuses RLN/RLS Class H Fuses

250/600 VAC • Renewable • 1 – 600 Amperes

Littelfuse RLN/RLS series renewable fuses are a quality product that have traditionally been used to provide low cost protection of general purpose feeder and branch circuits where available short-circuit currents do not exceed 10,000 amperes. However, increased levels of available fault current and the possibility that renewable fuses may be improperly renewed is a potential safety hazard. In addition, escalating labor costs and increasing automation, which makes downtime very expensive, have greatly reduced or eliminated the cost savings attributed to renewable fuses.

We recommend the use of POWR-PRO® FLSR_ID series Indicator® fuses for circuits between 250 and 600 volts and FLNR_ID series for circuits 250 volts and below. Complete information on POWR-PRO Indicator fuses may be found in the POWR-PRO fuse section of this catalog. FLNR fuses are in this section of the catalog.
