Ferraz Shawmut TRS4-1/2R - RK5 Class Fuse 600V 4A (200kA AIC)

Ferraz Shawmut TRS4-1/2R is a low-voltage current-limiting fuse designed for circuit protection in industrial electrical systems. This RK5-class TRS series fuse features a 600V AC rating with a 4A current capacity and 200kA interrupting rating at 600V for reliable short-circuit protection. The single-barrel design measures 0.56" in diameter with a compact 0.2 lb construction, meeting UL/CSA standards for safety compliance. Its Tri-Onic time-delay characteristic provides optimal motor circuit protection while resisting nuisance tripping from inrush currents. Typical applications include motor branch circuits, transformers, and power distribution equipment requiring high interrupting capacity.
