A6D8R - 8 Amp Fuse

A6D8R - 8 Amp Fuse

The Mersen A6D8R Amp-Trap 2000® Class RK1 Time-Delay Fuse is built for your electrical systems that need dependable protection without unnecessary shutdowns during startup. Rated at 8 Amps, this fuse is designed to handle temporary inrush currents from motors and equipment while still providing fast protection when overloads or short circuits occur.

In many commercial and industrial systems, equipment pulls extra current for a few seconds when starting up. A standard fuse can sometimes react too quickly and interrupt normal operation. The A6D8R is designed to help you avoid that issue. Its time-delay design allows normal startup surges to pass while still responding quickly during serious fault conditions to help protect motor starters, switches, control panels, and connected equipment from electrical damage.

Part of the trusted Amp-Trap 2000® A6D-R series, the A6D8R is commonly used in HVAC equipment, industrial machinery, branch circuits, and power distribution systems where reliable circuit protection matters. The built-in SmartSpot® indicator makes maintenance easier by providing a clear visual indication when the fuse opens, helping reduce troubleshooting time and making blown fuses easier to identify.

Its ferrule-style terminals provide secure clip mounting, while the PolyTube body is designed for dependable performance in demanding environments. It can also replace older Class H, K, and RK5 fuses already installed in existing systems.
