Cooper Bussmann DLS-R-20 - RK5 Time-Delay Fuse 20A 600V (200kA AIC)

Cooper Bussmann DLS-R-20 is a low-voltage current-limiting fuse designed for circuit protection in industrial electrical systems. This RK5-class fuse features a 600V AC/DC voltage rating and 20A current rating with a 200kA interrupting capacity at 600V for reliable short-circuit protection. Its single-barrel construction with time-delay characteristics provides selective coordination while resisting nuisance tripping from motor inrush currents. Compliant with UL/CSA standards, this fuse is engineered for use in panelboards, switchgear, and industrial control equipment requiring high fault current protection.
