Mersen A4BQ2500-TA
Fuse 600V 2500A Time-Delay Class L A4BQ Series TA Indicator
Product Description
The Amp-Trap 2000 A4BQ fuses offer a current limiting capability that exceeds other Class L fuses by 20 percent. When appropriately coordinated, these fuses provide exceptional protection for service entrance equipment, ensuring that downstream circuit components are safeguarded against short circuit let-thru currents.
Additionally, the A4BQ series incorporates a built-in time-delay feature that lasts for 4 seconds at 500 percent of the rated current. This characteristic allows the fuse to handle harmless inrush currents without triggering nuisance openings, thereby enhancing reliability in various applications.
