A6K30R - 30Amp Fuse

A6K30R - 30Amp Fuse

If you’re protecting equipment in a system with high available fault current, the Mersen A6K30R Amp-Trap® fuse is built for that job. This 30 amp Class RK1 fast-acting fuse is made to open quickly during overloads and short circuits, helping reduce damage to motors, controls, panels, and other electrical components before a fault spreads through the system.

The A6K30R is commonly used in commercial and industrial electrical setups where dependable overcurrent protection is important. Its ferrule-style design makes installation simple in compatible fuse holders, while the compact body fits easily into many control panel and distribution applications. Mersen also built this fuse with tin-plated copper terminals and a durable PolyTube body to help it hold up in demanding environments.

Rated for 600VAC and 300VDC, this fuse can be used in both AC and DC circuits. The high interrupting rating gives added protection in systems where fault currents can reach extreme levels. Whether it’s used in HVAC equipment, machinery, motor circuits, or feeder protection, the A6K30R delivers quick response and reliable performance without overcomplicating the job.
