Overview

The Mersen A60X400-4K Amp-Trap® Form 101 high speed fuse is engineered for critical protection of high-voltage, heavy-duty rectifiers, particularly in traction rectifier applications. This fuse excels at carrying sustained overloads common with demanding apparatus, ensuring operational continuity and equipment safety. Designed for robust performance, the A60X series is a reliable choice for safeguarding sensitive electronic components. The bolted blade design ensures secure connections and efficient current transfer. This specific model, SKU A60X400-4K, offers a 600VAC voltage rating and a 400A current rating, making it suitable for substantial power systems. The compact, hockey-puck design found in larger amperage sizes (700A through 2000A) within the A60X line allows for high power protection within a minimal footprint, a crucial factor in space-constrained industrial environments. Manufactured in the US, this fuse adheres to stringent quality standards. Its high-speed interruption capabilities are vital for preventing catastrophic damage from short circuits in rectifier circuits.
