A6K100R - 100Amp Fuse Description

A6K100R - 100Amp Fuse

The Mersen A6K100R Amp-Trap® Class RK1 Fast-Acting Fuse is built for your electrical systems where quick fault protection is critical. Rated at 100 Amps, this fuse is designed to respond fast during overloads and short-circuit conditions, helping protect electrical equipment before serious damage can occur.

In commercial and industrial environments, electrical faults can happen without warning. When they do, having the right fuse in place can make a big difference. The A6K100R is designed to limit damaging fault currents quickly, helping you reduce stress on switches, control panels, transformers, feeders, and other connected equipment. Its fast-acting design makes it especially useful in systems where sensitive electrical components need immediate protection.

Part of Mersen’s trusted Amp-Trap® A6K-R series, this Class RK1 fuse is commonly used in branch circuits, feeder circuits, and backup protection applications where high available fault currents are present. The blade-style terminals provide secure clip mounting, while the PolyTube insulating body is designed for dependable performance in demanding electrical environments.
