A6D9R - 9 Amp Fuse

A6D9R - 9 Amp Fuse

The Mersen A6D9R Amp-Trap 2000® Class RK1 Time-Delay Fuse is built for your electrical systems that need dependable protection without unnecessary downtime during startup. Rated at 9 Amps, this fuse is designed to handle the temporary inrush currents that motors and electrical equipment often create during normal startup while still providing fast protection when overloads or short circuits occur.

In real-world commercial and industrial environments, startup surges are part of everyday operation. A fuse that reacts too quickly can lead to nuisance openings, unexpected shutdowns, and wasted maintenance time. The A6D9R helps solve that issue with its time-delay design, allowing equipment to start normally while still responding quickly during serious fault conditions. That added protection can help you reduce damage to motor starters, switches, control panels, and other connected electrical components.

Part of the trusted Amp-Trap 2000® A6D-R series, the A6D9R also includes Mersen’s built-in SmartSpot® indicator. When the fuse opens, the visual indicator makes it easier for maintenance teams to quickly identify the blown fuse and get systems back online faster.

Its ferrule-style terminals provide secure mounting, while the PolyTube body is designed for dependable long-term performance in demanding environments.
