Overview

The Mersen AJT35ID Amp-Trap 2000® fuse offers robust circuit protection with advanced material technology, providing IEC Type 2 No Damage protection for main, feeder, and branch circuits across all load types. This Class J fuse operates at 600VAC and 400VDC, with a 35A rating. It features a SmartSpot® visual open fuse indicator for quick identification of blown fuses, eliminating the need for separate indicators. The time-delay characteristics are specifically engineered to effectively manage typical motor and transformer inrush currents, a common challenge in industrial applications. Simultaneously, the AJT35ID delivers superior current-limiting capabilities, safeguarding sensitive equipment from damaging overcurrents and short circuits. A significant advantage is its compact design, requiring only half the mounting space of comparable 600VAC Class RK fuses, which can lead to smaller panel sizes and cost savings. The ferrule termination ensures secure and reliable connections. This fuse is an ideal choice for applications demanding reliable protection, efficient space utilization, and clear fault indication.
