Mersen TR350R - TR Fuse 350A (200kA@250V RK5 Class)

Mersen TR350R is a low-voltage current-limiting fuse designed for circuit protection in industrial power distribution systems. This RK5-class TR-type fuse features a 250V AC rating with a 350A current capacity and 200kA interrupting rating at 250V for reliable short-circuit protection. The single-barrel construction measures 2.06" in diameter with a robust 1 lb design, meeting UL/CSA standards for safety. Its Tri-Onic time-delay characteristic provides optimal coordination with downstream devices while protecting against overloads. Typical applications include motor control centers, switchgear, and industrial control panels requiring high interrupting capacity.
