ABB AJT200 Class J Time-Delay Fuse 200 Amp 600V AC

The ABB AJT200 is a 200-amp Class J time-delay fuse designed for motor and general-purpose circuit protection in industrial and commercial applications. This current-limiting fuse provides reliable overcurrent protection with excellent short-circuit interrupting capacity rated at 200,000 amperes AC.

Key Features:

• 200 amp current rating at 600 volts AC
• Class J time-delay design for motor starting and inductive load protection
• Current-limiting technology reduces let-through energy during fault conditions
• 200kA interrupting rating (200,000 amperes at 600V AC)
• UL Listed and CSA Certified for North American installations
• Compact Class J dimensions for space-efficient installation
• Non-renewable cartridge fuse design

Class J fuses are current-limiting and provide superior protection for motor circuits, feeders, and branch circuits. The time-delay characteristic allows temporary overloads during motor starting while providing fast protection against short circuits. Suitable for use in panelboards, motor control centers, and combination motor starters where Class J protection is specified.
