Littelfuse KLKR025 25A Fuse
This Littelfuse KLKR025 is a 25 amp, fast-acting cartridge fuse rated for 600 VAC and 300 VDC. It suits industrial control panels, generator circuits and other equipment needing high-speed overcurrent protection with a 200000 A interrupting rating.
Check voltage and holder fit
Verify that your circuit operates at or below 600 VAC or 300 VDC and that the fuse holder accepts a 13/32 inch diameter by 1 1/2 inch length cartridge with rejection caps. The nylon body resists impact, abrasion and chemicals, so confirm the mounting environment matches those durability needs.
Sustained load behaviour
Under continuous load the fast-acting element opens quickly once current exceeds 25 amps, limiting let-through energy during faults. The 200000 A interrupting rating ensures safe clearance of high prospective short-circuit currents without sustained arcing.

Questions about this item
Does the Littelfuse KLKR025 come alone or in a pack, and is a fuse holder included?
The Littelfuse KLKR025 is supplied as a single 25 A cartridge fuse with a rejection cap; a compatible 13/32 in. diameter fuse holder or block must be purchased separately.
How do I know the 25 A, 600 VAC rating is the right choice for my circuit?
Select the KLKR025 only when the circuit requires exactly 25 amps and operates at or below 600 VAC or 300 VDC; the rejection cap prevents insertion into lower-rated holders, so the holder must accept 13/32 in. diameter fuses.
What does the 200000 A interrupting rating mean once the fuse is installed?
It means the KLKR025 can safely clear a short-circuit current up to 200000 A RMS symmetrical at 600 VAC without rupturing, protecting downstream components from severe fault energy.
