AJT10 - 10 Amp Fuse

AJT10 - 10 Amp Fuse

The AJT10 Class J Time-Delay Fuse is a practical choice for protecting your electrical systems that deal with motor startups, transformer inrush currents, and other temporary surges. Instead of opening every time equipment powers on, this fuse is designed to tolerate short-term startup loads while still reacting quickly during overloads and short circuits. That balance makes it a dependable option for many commercial and industrial applications.

Its compact Class J design is another advantage, especially in panels where space is limited. The AJT10 also includes a SmartSpot® visual indicator, making it easier to identify when the fuse has opened so maintenance crews can troubleshoot faster and get equipment back online with less delay.

Built with strong current-limiting protection, the AJT10 helps reduce the amount of fault energy passing through the system during a short circuit. That can help protect your connected equipment, wiring, and components from more serious damage. It’s commonly used in motor control centers, HVAC systems, transformers, industrial machinery, feeder circuits, and branch circuit protection where reliable performance matters day after day.

Key Features and Benefits

• Time-delay design helps prevent nuisance fuse openings during startup currents: Allows temporary inrush currents to pass without unnecessary interruptions.
• Current-limiting protection helps reduce damage during fault conditions: Helps minimize thermal and mechanical stress on connected electrical equipment.
• SmartSpot® indicator provides quick visual identification of an open fuse: Helps maintenance personnel troubleshoot and replace opened fuses more efficiently.
• Compact Class J size helps save panel space: Fits well into installations where enclosure space is limited.
• Rated for 200 kA interrupting capacity: Suitable for high fault-current commercial and industrial electrical systems.
• Suitable for AC and DC applications: Compatible with a variety of electrical distribution and protection systems.
