Mersen A070URD33LI0450 - Current-Limiting Fuse 450A (700V AC, 200kA AIC)

Mersen A070URD33LI0450 is a low-voltage current-limiting fuse designed for robust circuit protection in demanding industrial applications. It features a 700V AC voltage rating with a 450A current rating, providing reliable overcurrent protection in high-power systems. The fuse utilizes a square body PSC design with NA long blade connections and current-limiting LI technology to safely interrupt fault currents. Constructed to meet SB-3 class requirements, it delivers 200kA interrupting capacity at 700V with very fast (VF) clearing characteristics. This fuse is typically employed in industrial power distribution systems, motor control centers, and switchgear applications requiring high-performance circuit protection.
