Mersen A50QS90-4

The A50QS semiconductor fuse addresses the evolving demands of modern equipment, offering advanced protective features. With a maximum operating temperature of 80 °C and a minimum storage temperature of -25 °C, this fuse operates effectively in a variety of environments. Its lower I₂t rating enhances equipment protection, particularly in dynamic applications such as motor drives, inverters, and uninterruptible power supplies (UPS). Additionally, it provides extended lifespan under cyclic loading conditions and minimizes watt loss, making it suitable for critical applications.

This fuse has a rated voltage of 500V AC and DC, with an impressive breaking capacity of 50 kA. The connection terminal is crafted from tin-plated brass, designed for bolted mounting, while the body is made from GMG insulating material. With a diameter of 1 inch, the A50QS is optimized for high-speed performance and is classified under the Amp-Trap® series.
