Frequently Asked Questions

What is the LITTELFUSE KLK004 fuse used for?

The LITTELFUSE KLK004 is a fast-acting midget fuse used for overcurrent protection in industrial equipment. It safeguards sensitive circuits in control panels, motor drives, and power supplies where rapid response to short circuits is critical. Its 4 A rating and 600 V AC / 500 V DC capability make it suitable for general-purpose industrial applications.

What are the specifications of the LITTELFUSE KLK004?

The LITTELFUSE KLK004 is a KLK Series, midget, fast-acting cylindrical fuse rated at 4 A, 600 V AC, and 500 V DC. Its physical dimensions are 13/32 in x 1 1/2 in. The manufacturer part number is KLK004, and it is designed for overcurrent protection in industrial environments.

Where to buy LITTELFUSE KLK004 worldwide?
