Features
The Features is part of the Mersen (formerly Ferraz Shawmut) general purpose fuses line, distributed by Gross Automation.
Amp-trap 2000 SmartSpot AJT fuses now provide a visual open fuse indicator. With advanced material technology added to the existing product line the AJT fuse provides IEC Type 2 protection to main, feeder, and branch circuits, for all types of loads, yet they require only half the mounting space needed for 600VAC Class RK fuses.
