A6D30R - 30 Amp Fuse

A6D30R - 30 Amp Fuse

The Mersen A6D30R Amp-Trap 2000® Class RK1 time-delay fuse is designed for electrical systems that demand dependable circuit protection without unnecessary interruptions. Rated at 30 amps with both 600VAC and 600VDC capability, this fuse helps protect motors, feeders, branch circuits, and other electrical equipment from overloads and short circuits while still allowing temporary motor inrush currents during startup. That balance between fast fault response and controlled time delay makes it a trusted choice in commercial and industrial power distribution systems.

Part of Mersen’s well-known Amp-Trap 2000® A6D-R series, the A6D30R opens quickly under severe fault conditions to help reduce damage to motor starters, switches, and sensitive circuit components. At the same time, its time-delay performance helps prevent nuisance fuse openings that can interrupt operations and increase maintenance calls. The built-in SmartSpot® indication system gives technicians a quick visual signal when the fuse has operated, helping reduce troubleshooting time and improving maintenance efficiency.

The A6D30R is also a practical upgrade for existing systems because it can replace older 600V Class H, K, and RK5 fuses commonly found in the field. With a durable PolyTube body and tin-plated copper ferrule terminals, this fuse is built for long-term use in demanding environments such as manufacturing facilities, HVAC systems, pump applications, motor control centers, and commercial electrical distribution equipment.
