A2D25R - 25 Amp Fuse Description
A2D25R - 25 Amp Fuse
The Mersen A2D25R Amp-Trap 2000® fuse is a dependable choice for protecting your motors, feeders, and branch circuits in commercial and industrial electrical systems. Rated at 25 amps for 250VAC and 250VDC applications, this Class RK1 time-delay fuse is built to handle the everyday demands of equipment that experiences temporary startup surges.
Maintenance is easier, too. The built-in SmartSpot® indicator gives you a visible signal when the fuse has opened, making it quicker to spot and replace a blown fuse during troubleshooting.
