Siemens SLVBR4250 Fusible Bus Plug

Siemens Sentron SLVBR4250 Fusible Bus Plug is a 400 A, 240 V, 3‑phase, 4‑wire fusible bus plug designed for riser orientation in Siemens Sentron busway systems. The device provides integrated overcurrent protection and a disconnect at the bus plug level within a busway assembly, enabling modular protection of feeders along a powered distribution path. Configured for indoor use, it uses an IP40 enclosure to shield the fuse links and internal components. The SLVBR4250 is designed to mate with compatible Sentron busway segments, allowing scalable protection in industrial and commercial power‑distribution installations. With its 3P4W configuration, the unit carries three phase conductors plus a neutral, supporting typical feeders in distributed networks while maintaining a compact footprint within the busway corridor.
