LLSRK012ID - 12Amp Fuse Description
LLSRK012ID - 12Amp Fuse
A blown fuse is a small component that can cause a surprisingly big headache. Equipment stops, maintenance gets called, and someone suddenly spends valuable time figuring out which fuse opened and why. The Littelfuse LLSRK012ID 12 Amp Class RK1 time-delay indicating fuse makes that situation easier to manage. With its built-in blown-fuse indicator, high interrupting capacity, and time-delay protection, it offers several practical advantages for industrial and commercial electrical systems.
Part of the Littelfuse POWR-PRO LLSRK_ID series, this industrial cartridge fuse features patented Indicator™ technology. When your fuse opens, a small indicator window darkens, giving maintenance technicians a clear visual cue about which fuse needs attention. It's a simple feature, but anyone who has spent time checking multiple fuses inside a control panel can appreciate the difference.
