A6K175R - 175Amp Fuse

A6K175R - 175Amp Fuse

The Mersen A6K175R Amp-Trap® Class RK1 Fast-Acting Fuse is built for your electrical systems that need dependable protection when fault conditions happen. Rated at 175 Amps, this fuse helps protect your branch circuits, feeder circuits, and connected equipment from overloads and short circuits before they create larger problems across the system.

In commercial and industrial settings, electrical faults can lead to damaged equipment, lost production time, and expensive repairs. The A6K175R is designed to respond quickly, helping reduce the amount of fault current passing through the system during an electrical event. That quick action can help you protect transformers, disconnects, control panels, switchboards, and other important electrical equipment used every day in demanding applications.

Part of the 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 allow for secure clip mounting, while the PolyTube body is designed for dependable day-to-day performance in commercial and industrial environments.

With a high 200 kA interrupting rating, the A6K175R works well in manufacturing facilities, HVAC systems, industrial machinery, commercial buildings, and power distribution equipment where fast fault clearing helps reduce downtime and equipment damage.
