Bussmann KTK-R-20

Overview

The Bussmann KTK-R-20 is a Class CC current-limiting fast-acting fuse designed for reliable protection of industrial and commercial circuits. With a 20 A current rating and 600 V voltage rating, it provides dependable short-circuit protection for sensitive equipment and branch circuits. Its 200 kAIC interrupt rating ensures robust fault current protection in high-energy environments.

Engineered with a fast-acting response, the KTK-R-20 is ideal for protecting control panels, general lighting, and distribution circuits where precise fault interruption is critical. Its rejection-style design prevents misapplication, while the ferrule end x ferrule end connection ensures secure installation. Built with a durable melamine tube body, this fuse offers long-lasting reliability.
