Renewable fuse, Classe H
1 - 600 A, 250 VAC | RLN series Littelfuse

Littelfuse RLN 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, generally increased levels of available fault current and the distinct possibility that renewable fuses may be improperly renewed, rendering them unsafe, have all but eliminated the use of these fuses in new applications. 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 IDSR series Indicator™ fuses for circuits between 250 and 600 volts and FLNR series for 250 volt and below circuits. Complete information on POWR-PRO Indicator fuses may be found in the POWR-PRO Section of this catalog. FLNR fuses are in this section of the catalog.
