A6K3R - 3Amp Fuse Description
A6K3R - 3Amp Fuse
The Mersen A6K3R Amp-Trap® fuse is designed to help protect electrical systems from overloads and short circuits before they turn into bigger problems. With a 3 amp rating and fast-acting performance, this Class RK1 fuse is a dependable choice for industrial equipment, control panels, feeder circuits, and commercial power distribution systems.
Built for applications where high fault currents are present, the A6K3R features a 200 kA interrupting rating to help protect connected equipment during serious electrical events. Its current-limiting design helps reduce the amount of energy that reaches downstream components, which can help lower the risk of damage and unnecessary downtime.
This fuse is rated for 600VAC and 300VDC applications and uses a ferrule-style design that installs easily in clip-mounted fuse holders. Mersen also designed the A6K3R with tin-plated copper terminals and a durable PolyTube body for reliable performance in demanding environments.
Whether you're replacing a fuse in existing equipment or maintaining a commercial electrical system, the A6K3R offers the straightforward protection electricians and maintenance professionals rely on every day.
