The TR2R is a high-performance, current-limiting time-delay fuse from Mersen’s Tri-Onic TR-R series. Categorized as a Class RK5 fuse, it is a staple in industrial electrical protection. It is specifically designed to handle the temporary inrush currents of motors and control transformers without "nuisance tripping," while still providing a high degree of current limitation to protect downstream components from short-circuit damage.
