Description
The Mersen AJT200/400 Class J time-delay fuse is designed to provide a reliable, permanent solution for reducing current ratings without resorting to temporary fuse reducers. It offers the same protection levels as traditional AJT fuses but is housed in a larger body, making it suitable for high-demand applications while ensuring safety and reliability.
Key Features
- Permanent Solution: Acts as a permanent replacement for traditional temporary-use fuse reducers.
- Arc Flash Energy Reduction: Recommended to help reduce arc flash energy, enhancing safety.
- Current-Limiting Performance: Extremely current-limiting with a low peak let-thru current; among the most current-limiting UL class fuses.
- Time-Delay Characteristics: Provides time-delay protection suitable for motor starting and transformer inrush.
