Littelfuse KLNR100 LFSE KLNR100 FUS 250V F/A CLASS RK1

Product Description

Littelfuse KLNR100 offers reliable overload and short-circuit protection. This fuse is part of the KLNR/KLSR series which was among the first current-limiting fuses. Its design features a single-element, silver link which acts quickly during faults. It is suitable for protecting inductive loads like motors and transformers. However, it must be oversized to avoid tripping due to harmless inrush currents.

• Reliable interruption of currents up to 200,000 amperes.
• Fast-acting protection for sensitive equipment.
• Current-limiting design reduces equipment damage.

Product Highlights

The KLNR100 is designed to meet the rigorous demands of various electrical applications including DC control circuits and solar systems. It provides fast-acting protection for devices such as variable speed drives and rectifiers. Lacking in indication, this fuse ensures dependable power management without unnecessary delays during faults.
