LLNRK035 - 35Amp Fuse

LLNRK035 - 35Amp Fuse

When electrical equipment starts up, the current doesn't always rise gradually. Motors, transformers, and other inductive loads can draw a brief surge of electricity before settling into normal operation. That's why selecting the correct fuse involves more than matching an amperage rating. You also need the right time-delay characteristics, voltage rating, interrupting capacity, and physical fit.

Think about what happens when a motor starts. For a short period, its current draw may be several times higher than its normal running current. A fuse without suitable time-delay characteristics could open during that expected startup event. The LLNRK035 uses a dual-element design, including a thermally reversible, spring-loaded thermal overload element, to accommodate appropriate short-duration current increases while responding to sustained overload conditions.
