A6D110R - 110 Amp Fuse

A6D110R - 110 Amp Fuse

The Mersen A6D110R Amp-Trap 2000® fuse is built for your electrical systems that can’t afford unnecessary downtime. Rated at 110 amps, this Class RK1 time-delay fuse is designed to protect motors, feeders, branch circuits, and industrial equipment from damaging overloads and short circuits while still handling the temporary startup surges that are common in commercial and industrial applications.

When large motors or heavy equipment power on, they often draw a brief spike in current. Standard fuses can sometimes react too quickly and open even when the system is operating normally. The A6D110R is designed to avoid that problem. Its time-delay performance allows normal inrush currents to pass during startup, while still providing fast protection if a real fault occurs. That balance helps reduce nuisance interruptions and can help protect expensive electrical equipment from damage.

Mersen also added its SmartSpot® visual indicator, making maintenance easier by providing a quick way to identify when the fuse has opened. In busy facilities, small details like that can save valuable troubleshooting time. The fuse itself is built with tin-plated copper blade terminals for dependable conductivity and a durable PolyTube body designed for long-term performance in demanding environments.

Another reason the A6D110R is commonly used in upgrades and replacements is its ability to replace older Class H, K, and RK5 fuses already installed in many systems. Combined with a 200 kA interrupting rating, this fuse provides the level of protection needed in applications where available fault currents are high and reliable performance matters every day.
