Mersen 600V 2-1/4A CLASS J TD FUSE | AJT2-1/4

Description

The Mersen AJT2-1/4 Class J time-delay fuse is engineered for efficient protection in compact settings. This fuse is designed to offer IEC Type 2 No Damage protection across various circuit types including mains, feeders, and branches. Its time-delay features are suitable for managing inrush currents from motors and transformers, while its compact design allows for space-saving and economical fuse block usage.

Key Features

• Visual Indicator: Includes a non-indicating option or SmartSpot visual blown fuse indicator for easy status monitoring.
• Time-Delay: Effectively handles motor starting and transformer inrush currents.
• High Interrupting Rating: 300kA interrupting rating with self-certified, UL witnessed tests.
• Current-Limiting: Provides extreme current-limiting for low peak let-thru current; recognized as the most current-limiting UL class fuse.
• Arc Flash Energy Reduction: Recommended to enhance safety by reducing arc flash energy.
• Compact Footprint: Requires less mounting space, allowing use of smaller, more cost-effective fuse blocks.
• 2-to-1 Selectivity: Facilitates easy selectivity to avoid nuisance shutdowns.
• Class J Dimensions: Unique dimensions prevent incorrect replacements.
• Identification: High-visibility orange label and metal-embossed date/catalog number for clear identification.
