LLSRK009ID - 9Amp Fuse

LLSRK009ID - 9Amp Fuse

A blown fuse shouldn't turn into a lengthy troubleshooting job. The Littelfuse LLSRK009ID 9 Amp Class RK1 time-delay indicating fuse helps maintenance teams find the problem faster while providing dependable overcurrent protection for industrial and commercial electrical equipment. Part of the Littelfuse Powr-Pro LLSRK_ID series, this fuse features patented Indicator™ technology. When your fuse opens, its indicator window darkens, giving technicians a quick visual way to identify the affected circuit.

Built for applications where electrical equipment may experience brief current surges, the LLSRK009ID combines time-delay performance with Class RK1 current-limiting protection. Its precision-formed short-circuit elements help limit damage from electrical faults, while a solid-state overload section eliminates the moving parts found in some spring-loaded fuse designs. That means fewer opportunities for fatigue-related failures and unnecessary interruptions.
