Description
The Mersen AJT125/400 fuse is a time-delay Class J fuse designed to safely reduce current ratings without the need for temporary fuse reducers. It delivers the same protection levels as traditional AJT fuses but in a larger fuse body, providing reliable IEC Type 2 No Damage protection for motors, transformers, and other circuits. This fuse is ideal for applications where downsizing without compromising safety and performance is crucial.
