Mersen A2K12R A6K-R Series Class RK1 Fast-Acting Fuse

Mersen A2K12R A6K-R Series Class RK1 Fast-Acting Fuse

The Mersen A6K-R Series Amp-Trap® fuse is a current-limiting, Class RK1 fast-acting fuse engineered for branch/feeder circuit protection and back-up protection where high available short-circuit currents exist. Rated 600VAC / 300VDC with an AC Max I.R./Breaking Capacity of 200 kA, this fuse is built for demanding commercial and industrial power distribution systems. This family is available with either Blade or Ferrule connection types to match standard fuse holders and fuse blocks, both using tin-plated copper connection/terminal material for dependable conductivity. The fuse is RoHS Compliant for environmental compliance and rated for 50/60 Hz electrical systems.
