LLSRK030ID - 30Amp Fuse

LLSRK030ID - 30Amp Fuse

Electrical protection shouldn't make troubleshooting harder than it needs to be. When your equipment unexpectedly shuts down, maintenance teams need to identify the problem quickly, protect valuable components, and restore normal operation with minimal disruption.

With a 30 amp continuous current rating, 600V AC maximum voltage, and 300V DC maximum voltage, the Littelfuse LLSRK030ID is built for applications requiring Class RK1 current-limiting protection. Its Slo-Blo time-delay characteristics let it accommodate brief current surges, such as those during equipment startup, without opening unnecessarily. That means fewer avoidable interruptions when the fuse is correctly selected for the circuit.
