A6D35R - 35 Amp Fuse

A6D35R - 35 Amp Fuse

The Mersen A6D35R Amp-Trap 2000® Class RK1 time-delay fuse is built for electrical systems that need dependable protection without constant interruptions. Rated at 35 amps for both 600VAC and 600VDC applications, this fuse helps protect motors, feeders, branch circuits, and other electrical equipment from overloads and short circuits while still allowing temporary startup surges to pass normally.

In many industrial and commercial systems, motors pull extra current for a brief moment during startup. Standard fuses can sometimes react too quickly and create unnecessary downtime. The A6D35R is designed to handle those short inrush currents while still opening fast during serious fault conditions. That helps reduce the risk of damage to motor starters, switches, contactors, and connected equipment while keeping operations moving.

One feature that makes day-to-day maintenance easier is the built-in SmartSpot® indication system. When the fuse opens, technicians can quickly identify the affected fuse without spending extra time troubleshooting. In busy facilities, that can help reduce downtime and simplify maintenance work.

The A6D35R is also commonly used as a replacement for older Class H, K, and RK5 fuses already installed in existing systems. Its ferrule-style design fits many common applications, making upgrades and replacements more straightforward for electricians and maintenance teams. With a durable PolyTube body and tin-plated copper terminals, this fuse is designed for long-term use in demanding environments like HVAC systems, manufacturing equipment, motor control centers, and commercial distribution panels.
