Description
The Mersen AJT45 is a Class J time-delay fuse designed to offer superior protection with advanced material technology. It provides IEC Type 2 No Damage protection for a range of circuits and loads, requiring only half the mounting space of traditional 600VAC Class RK fuses.
Key Features
- SmartSpot Indicator: Includes a visual SmartSpot indicator to easily identify blown fuses.
- Time-Delay Characteristics: Ideal for handling inrush currents from motors and transformers.
- High Interrupting Rating: 300kA interrupting rating with UL witnessed tests.
- Superior Current-Limiting: Among the most current-limiting fuses available, effectively minimizing peak let-thru current.
- Arc Flash Energy Reduction: Recommended for reducing arc flash energy.
- Compact Design: Requires less mounting space, allowing use of smaller, more economical fuse blocks.
- Easy Selectivity: Provides easy 2-to-1 selectivity to prevent nuisance shutdowns.
- Error Prevention: Unique Class J dimensions help prevent incorrect replacements.
