A2K90R - 90Amp Fuse

A2K90R - 90Amp Fuse

The Mersen A2K90R Amp-Trap® Class RK1 fuse is made for electrical systems that need quick, reliable protection from overloads and short circuits. With a 90 amp rating and fast-acting performance, it helps protect your equipment before damage spreads through the system. It’s often used in branch circuits, feeder circuits, control panels, and other applications where keeping your equipment running safely is important.

This fuse is rated for both 250VAC and 250VDC applications, making it a versatile option for a wide range of commercial and industrial electrical systems. Its current-limiting design helps reduce the amount of energy that passes through during a fault, which can help protect connected components and lower the risk of costly repairs.
