A6K12R - 12 Amp Fuse

A6K12R - 12 Amp Fuse

The A6K12R Class R Fast-Acting Fuse is made for your electrical systems that need quick protection when fault conditions happen. Rated at 12 Amps, this current-limiting fuse helps protect branch circuits, feeder circuits, and connected equipment from overloads and short circuits before they cause larger problems.

Electrical faults can happen without much warning, especially in commercial and industrial environments where equipment runs daily under demanding conditions. The A6K12R is designed to respond quickly during those events, helping reduce the impact on control panels, disconnects, transformers, and other important electrical components. Its fast-acting design helps clear fault currents rapidly, which can help you reduce equipment damage and cut down on downtime.

The cartridge-style construction allows for secure installation in compatible fuse holders and disconnects, while the non-indicating design keeps the fuse simple and dependable for everyday applications. This fuse is commonly used in systems where high available fault currents exist and reliable overcurrent protection is important.

With a high 200 kA interrupting rating at 600VAC, the A6K12R is well suited for commercial and industrial power distribution systems where fast fault clearing is needed to help protect electrical equipment.
