A6K500R - 500Amp Fuse

A6K500R - 500Amp Fuse

The Mersen A6K500R Amp-Trap® Class RK1 Fast-Acting Fuse is designed for your electrical systems that need dependable protection under demanding conditions. Rated at 500 Amps, this fuse helps protect your branch circuits, feeder circuits, and connected equipment from overloads and short-circuit conditions before they can lead to equipment damage or unexpected downtime.

In commercial and industrial environments, electrical faults can place serious stress on power distribution systems. The A6K500R is built to respond quickly during fault conditions, helping reduce the amount of fault current moving through the system. That fast action can help protect transformers, switchboards, disconnects, motor control equipment, and other electrical components commonly found in high-demand applications.

Part of Mersen’s trusted Amp-Trap® A6K-R series, this Class RK1 fuse is commonly used in systems where high available fault currents are present. The blade-style terminals provide secure clip mounting, while the PolyTube body is designed for dependable day-to-day performance in industrial and commercial environments.

With a high 200 kA interrupting rating, the A6K500R works well in manufacturing facilities, commercial buildings, HVAC systems, industrial machinery, and electrical distribution equipment where reliable overcurrent protection is important.
