ABB AJT150 Time Delay Fuse 150 Amp 600V Class J

The ABB AJT150 is a 150-amp Class J time delay fuse designed for superior overcurrent protection in commercial and industrial electrical systems. This UL Listed fuse provides reliable branch circuit and equipment protection with a 600-volt AC rating and 200,000 amp interrupting capacity.

Key Features:

• 150-amp current rating for medium to heavy-duty applications
• Class J design with dimensional rejection feature prevents incorrect fuse installation
• Time delay characteristic allows temporary overloads during motor starting and inrush conditions
• 600V AC rated for broad compatibility with industrial power systems
• 200kA interrupting rating (AIR) provides robust short-circuit protection
• Current-limiting design reduces let-through energy and protects downstream equipment
• Compact footprint saves panel space compared to other fuse classes
• Non-renewable cartridge design ensures consistent performance

The AJT series fuses are ideal for motor circuits, transformers, capacitor banks, and general power distribution where selective coordination and space savings are priorities. These fuses meet UL 248-8 standards and are suitable for use in panelboards, switchboards, and motor control centers.
