Bussmann DLN-R-45 - RK5 Time-Delay Fuse 45A (200kA AIC @ 250V)

The Bussmann DLN-R-45 is a current-limiting, time-delay fuse from the Dura-Lag family designed to provide reliable overcurrent protection in low voltage electrical systems. It features a 45A current rating and a 250V AC voltage rating, capable of interrupting up to 200kA of fault current. Constructed as a single-barrel fuse with an RK5 classification, it offers a high degree of current limitation and a time-delay characteristic to prevent nuisance tripping from harmless temporary overloads. This fuse complies with industry standards for safety and performance in demanding applications. It is typically used for protecting motor circuits, transformers, and feeder circuits in industrial and commercial power distribution systems.
