A2K225R - 225Amp Fuse

A2K225R - 225Amp Fuse

The Mersen A2K225R Amp-Trap® Class RK1 Fast-Acting Fuse is built for electrical systems that can’t afford unnecessary downtime. Rated at 225 amps and designed for both 250VAC and 250VDC applications, this fuse provides you a fast overcurrent protection for branch circuits, feeder circuits, and other power distribution equipment exposed to high available fault currents.

What makes the A2K225R stand out is its fast-acting, current-limiting performance. When a fault occurs, the fuse reacts quickly to help you limit damage to connected equipment and reduce the chance of larger system issues. That added protection can make a real difference in industrial and commercial environments where reliability and uptime matter.

Its Class RK1 design and high interrupting rating make it a solid fit for demanding electrical applications, including control panels, motor control centers, and OEM equipment.
