LLSRK600ID - 600Amp Fuse Description
LLSRK600ID - 600Amp Fuse
A blown fuse is inconvenient enough. Having to check several fuses to find the problem makes it worse, especially when your production line is waiting to get back up and running.
The Littelfuse LLSRK600ID 600A Class RK1 time-delay indicating fuse helps reduce that frustration in electrical maintenance. Its built-in indicator window darkens when the fuse opens, giving technicians a quick visual way to identify which fuse needs attention: no unnecessary guessing, and less time spent tracking down the affected circuit.
Large motors and heavy machinery can draw a considerable amount of current during startup. Those brief surges are normal during operation, but they can cause problems if a fuse opens unnecessarily. The LLSRK600ID uses a time-delay design that lets it handle temporary current increases while still protecting against overloads and short circuits.
