LLSRK001ID - 1Amp Fuse

LLSRK001ID - 1Amp Fuse

A blown fuse shouldn't turn into a lengthy troubleshooting session. When your electrical equipment stops working, identifying the problem quickly can make a real difference. The Littelfuse LLSRK001ID makes fault identification easier while delivering dependable overcurrent protection for appropriately rated electrical circuits.

But the LLSRK001ID offers more than its indicator. Its solid-state overload section contains no moving parts, eliminating the mechanical fatigue associated with spring-loaded overload mechanisms.
