Mersen Protistor® A130UD70TTI80 (R301016) — Protistor Size 70 Square‑Body High‑Speed Fuse, 80 A, 1250 V AC (IEC) / 1300 V AC (UL), aR Semiconductor Characteristic, Striker Indicator, Bolted Flush Ends — Pack of 3

The Mersen Protistor® A130UD70TTI80 (item R301016) is a Size 70 square‑body, ultra‑fast aR fuse‑link designed specifically for semiconductor protection in high‑voltage power conversion equipment. Rated for 80 A and 1250 V AC (IEC) / 1300 V AC (UL), this bolted‑mount fuse features silver‑plated brass flush ends with UNC threads, an integral striker (indication) system, and ceramic body construction. Supplied as a pack of 3, Protistor® fuse‑links use die‑cut silver elements embedded in solidified sand to control arc behavior, minimize I²t and provide high interrupting capability.
