Overview

The Mersen Z300080 (SKU: Z300080) is a high-speed aR fuse-link from the Protistor® series, engineered for superior protection of power semiconductor devices. This fuse-link is rated for 690VAC (IEC) and 700VAC (UL), with a substantial current rating of 800A. Designed for applications requiring ultra-fast response, it effectively safeguards diodes, thyristors, and IGBTs within power conversion equipment. The construction features die-cut elements embedded in solidified sand, which facilitates controlled arcing and results in significantly lower I²t values, crucial for minimizing thermal stress on protected components. Its high interrupting rating further enhances safety and reliability. For optimal electrical performance and longevity, all contact surfaces are silver-plated, ensuring superior conductivity and resistance to corrosion. The use of non-magnetic hardware is a key design element for maintaining stability in high-frequency operating environments, preventing unwanted magnetic interference. The Z300080 is equipped with a low-voltage trip indicator, enabling activation of a microswitch for remote signaling or control system integration. Installation is facilitated by flush ends and metric thread mounting, providing a secure and precise fit in various global mounting configurations. The Size 33 designation indicates its specific physical dimensions, ensuring compatibility with standard fuse holders and equipment designed for this size. The Mersen Z300080 Protistor® fuse-link offers a reliable and precise solution for critical semiconductor protection needs.
