Bussmann DLN-R-300 - RK5 Class Fuse 300A (200kA AIC @ 250V)

Bussmann DLN-R-300 is a current-limiting fuse from the Dura-Lag family designed to provide reliable overcurrent protection in low voltage industrial applications. It features a 300A current rating and 250V voltage rating with a high 200kA interrupting capacity at 250V for superior short-circuit protection. The fuse utilizes a single-barrel RK5 class construction with time-delay characteristics that prevent nuisance tripping from motor starting currents. This Eaton-manufactured component meets industry standards for industrial power distribution systems, motor branch circuits, and feeder protection where durable, high-performance circuit protection is required.
