A2K15R - 15Amp Fuse

A2K15R - 15Amp Fuse

If you’re protecting electrical equipment in a system with high available fault current, the Mersen A2K15R Amp-Trap® fuse is built to handle the job. This 15A Class RK1 fast-acting fuse is designed to react quickly during overloads and short circuits, helping reduce damage to connected components and keeping downtime to a minimum.

The A2K15R is commonly used in industrial and commercial electrical systems where dependable circuit protection matters. Its fast-acting performance makes it a strong option for branch circuits, feeder circuits, control panels, HVAC equipment, and machinery that need rapid fault interruption. When a fault occurs, this fuse is designed to clear the issue quickly before it spreads through the system.

Mersen built this fuse with a compact ferrule design that installs easily into compatible fuse clips. The tin-plated copper terminals provide solid electrical contact while helping resist corrosion over time. With a 200 kA interrupting rating, the A2K15R is made for demanding environments where higher fault currents are present and reliable protection is critical.

Instead of overcomplicating things, this fuse does exactly what professionals expect it to do — provide fast, reliable protection for valuable electrical equipment.
