Littelfuse BLF Fuses Provide Exceptional Supplemental Overcurrent Protection
Product Status| Activei
info

The BLF series fast-acting fuses supplement the primary branch-circuit fuse or breaker to provide backup overcurrent protection. These fuses also have the capability to limit currents with fast-acting reliability, opening within seconds of being exposed to overloads and short circuits. They are suitable for control circuit and instrument protection in dry (exhibiting little to no humidity) locations. The BLF fiber tube fuses are the lowest-priced midget fuses available.
