A6K225R - 225Amp Fuse

A6K225R - 225Amp Fuse

The Mersen A6K225R Amp-Trap® Class RK1 Fast-Acting Fuse is built for your electrical systems where dependable overcurrent protection is important. Rated at 225 Amps, this fuse helps protect your branch circuits, feeder circuits, and connected equipment from overloads and short circuits before they can create larger electrical problems.

In commercial and industrial settings, electrical faults can damage equipment quickly if they are not cleared fast enough. The A6K225R is designed to respond quickly during fault conditions, helping reduce the amount of fault current moving through the system. That fast action can help protect your transformers, disconnects, switchboards, control panels, and other electrical equipment used in day-to-day operations.

With a 200 kA interrupting rating, the A6K225R works well in manufacturing facilities, commercial power systems, industrial machinery, HVAC equipment, and other applications where fast fault clearing helps reduce downtime and equipment damage.
