Mersen/Ferraz Shawmut A4BQ600 Amp-Trap 2000 Class L Time-Delay Fuse, 600A, 600VAC/500VDC

The A4BQ600 is a current-limiting power fuse engineered to offer up to 20% more current limitation than any other Class L fuse on the market. Its robust design makes it an ideal choice for large-load protection, effectively reducing Arc Flash energy and shielding sensitive equipment from the destructive effects of short-circuit let-thru currents.

Key Features:

Time-Delay Characteristic: Features a built-in 4-second time delay (at 500% of rated current) to accommodate harmless inrush currents from motors or transformers without nuisance opening.

Superior Protection: Provides maximum protection for downstream components when correctly coordinated, ensuring Type 2 "No Damage" protection.

High Interrupting Capacity: Safely interrupts fault currents up to 200kA AC and 100kA DC (self-certified up to 300kA).

Rugged Construction: Built with a fiberglass body (GMG) for exceptional dimensional stability in harsh industrial environments and high-grade silica filler for rapid arc quenching.

Rejection Style: Unique design prevents replacement by incorrect fuse classes when used with recommended fuse blocks.
