AJT5 – Mersen | 600V 5A CLASS J TD FUSE

Description

The Mersen AJT5 is a time-delay 5A Class J fuse rated for 600V AC and 400V DC, designed to provide reliable current-limiting protection for main, feeder, and branch circuits across a wide range of loads. The Amp-Trap 2000® AJT fuse features time-delay characteristics that help handle typical motor and transformer inrush currents while providing superior current-limiting performance. Its compact Class J design requires significantly less mounting space than traditional 600V Class RK fuses, making it a practical choice for applications where panel space is limited.
