A2D10R - 10 Amp Fuse

A2D10R - 10 Amp Fuse

The Mersen A2D10R Amp-Trap 2000® fuse is a practical choice for protecting motors, branch circuits, and electrical distribution systems where reliability matters. Rated for 10 Amps and designed for 250VAC/250VDC applications, this Class RK1 time-delay fuse is made to handle the quick surge of current that happens when motors start up, while still reacting fast during dangerous fault conditions. That combination helps reduce unnecessary fuse openings and protects connected equipment from costly damage.

For maintenance teams, small details can make a big difference. The built-in SmartSpot® indicator gives a clear visual signal when the fuse opens, helping speed up troubleshooting and reducing time spent searching through panels. Its compact ferrule design also makes installation simple in many existing fuse holders and control systems.
