Overview

The Mersen A2Y80-4 Amp-Trap® fuse, SKU A2Y80-4, is a specialized current-limiting fuse designed for robust protection in demanding industrial applications. With a voltage rating of 250VAC and 500VDC, and a current rating of 80A, this Type 4 blade fuse offers significant current limitation capabilities for both AC and DC circuits. Its unique rejection dimensions ensure it cannot be replaced by other fuse classes, preventing improper application and maintaining system integrity. The glass melamine body and plated terminals contribute to superior reliability, even in harsh environments. While the provided catalog content details other Mersen fuse series like A4BT and A4BY with higher voltage and current ratings, the A2Y series, as represented by the A2Y80-4, is specifically noted for its Type 4 blade configuration and its suitability for DC applications up to 500VDC. This fuse is ideal for protecting mains, feeders, and general circuits where precise current limitation and DC voltage handling are critical. Its construction ensures uniform characteristics across its ampere rating, providing consistent performance. Manufactured in the US, the A2Y80-4 is a reliable choice for specialized fusing needs.
