Overview

The Mersen Protistor® Size 91 aR fuse-link (SKU: B076062) offers robust semiconductor protection for power conversion equipment, operating at 1500VAC with a 160A rating. Engineered with a square body and DIN 140 blades, this fuse-link features a striker for trip indication. Its pure silver die-cut elements are embedded in solidified sand, ensuring controlled arcing characteristics for low I²t values and high breaking capacity. All contact surfaces are silver-plated, and hardware is non-magnetic. The integrated low-voltage trip-indicator can activate a field-mountable microswitch, even while the fuse is in service, providing enhanced operational safety and monitoring capabilities. This fuse-link is designed to protect sensitive semiconductor devices such as SCRs, diodes, thyristors, GTOs, and IGBTs. Its construction prioritizes reliability and performance in demanding electrical systems. The Mersen Protistor® series provides maximum flexibility in equipment design, with various body sizes and mounting styles available to suit diverse applications. This specific unit, with its aR rating, is optimized for fast-acting protection against short circuits in high-power semiconductor applications. Key specifications include a rated breaking capacity of 200 kA and a power dissipation of 200 W at In. The pre-arcing I²t is 465 kA²s, and clearing I²t at rated voltage is 2700 kA²s. This fuse-link is built to the IEC standard.
