A6K20R - 20Amp Fuse

A6K20R - 20Amp Fuse

The Mersen A6K20R Amp-Trap® Class RK1 Fast-Acting Fuse is a straightforward solution for protecting your electrical systems from overloads and short circuits. Rated at 20 Amps, this fuse is commonly used in commercial and industrial equipment where quick fault protection helps keep systems running and reduces the risk of damage to connected components.

When a fault occurs, every second counts. The A6K20R is designed to open quickly under short-circuit conditions, helping limit the amount of fault current moving through the system. That fast response can help protect transformers, control panels, disconnects, HVAC equipment, and other electrical gear that facilities rely on every day.

Part of Mersen’s trusted Amp-Trap® A6K-R series, this Class RK1 fuse is built for applications where high fault current protection is important. The ferrule-style terminals provide secure clip mounting, while the PolyTube body is designed for dependable performance in demanding electrical environments.

With a 200 kA interrupting rating, the A6K20R works well in power distribution systems, manufacturing equipment, industrial machinery, and commercial electrical applications where reliable overcurrent protection is needed.
