ABB AJT100 100 Amp Class J Time Delay Fuse 600V

The ABB AJT100 is a 100-amp Class J time delay fuse designed for superior overcurrent protection in commercial and industrial electrical systems. This current-limiting fuse provides reliable circuit protection with a 600-volt AC rating and features a time delay characteristic that allows temporary overloads while protecting against short circuits.

Key Features:

• 100 amp current rating with Class J specifications per NEC standards
• Time delay design allows motor starting currents and other temporary overloads
• Current-limiting technology reduces potential damage from fault currents
• 600 VAC voltage rating for demanding industrial applications
• 200kA interrupting rating (IR) at 600V AC for maximum protection
• Compact dimensions fit standard Class J fuse clips and holders
• UL Listed and meets NEC Class J requirements

Class J fuses are current-limiting and dimensionally compatible with standard fuse holders, making them ideal for motor controls, branch circuits, and feeder protection. The time delay characteristic prevents nuisance tripping during normal startup conditions while providing fast response to fault conditions.
