Overview

Mersen Protistor® Size 93 aR 1500VAC 750A square body fuse-link (SKU: S076123) delivers precise protection for high-power semiconductor applications. Designed for AC systems up to 1500VAC, this fuse-link provides a rated breaking capacity of 150kA, ensuring reliable interruption of fault currents in demanding industrial environments. The pure silver die-cut fuse element embedded in solidified sand optimizes arcing characteristics, minimizing I²t values for superior thermal management and reduced stress on protected components. With a current rating of 750A, this fuse-link is engineered for SCRs, diodes, thyristors, GTOs, and IGBT devices in power conversion equipment. The square body design with DIN 140 blades offers compatibility with global mounting standards, while the integrated striker mechanism enables remote indication via a field-mountable microswitch. All contact surfaces are silver-plated for low resistance, and non-magnetic hardware ensures consistent performance in high-frequency applications. The low-voltage trip indicator provides visual status confirmation, allowing for quick diagnostics without system shutdown. This fuse-link is part of Mersen’s Protistor® PSC series, known for state-of-the-art protection in semiconductor circuits. Ideal for renewable energy inverters, motor drives, and industrial power supplies where high reliability and fast response are critical.
