Why Choose the Mersen AJT10 Amp-Trap 2000® Fuse?
The Mersen AJT10 is a premium Class J time-delay current-limiting fuse designed to provide superior protection for industrial and commercial electrical systems. Part of the renowned Amp-Trap 2000® AJT series, it combines excellent current limitation with a time-delay characteristic that accommodates motor starting currents and transformer inrush without nuisance operation, while delivering exceptional protection against overloads and short circuits.
The AJT10 is engineered using advanced material technology to provide IEC Type 2 "No Damage" protection for properly coordinated motor starters, helping reduce downtime and equipment replacement costs. Its compact Class J footprint requires only half the mounting space of many Class RK fuse installations, making it ideal where panel space is limited.
Rated at 10 A, 600 V AC and 400 V DC, the Mersen AJT10 is suitable for mains, feeders, branch circuits, motor circuits, transformers, control panels, lighting and heating applications requiring dependable time-delay protection.
