Schneider Electric SD9354 Fusible Bus Plug Assembly

Schneider Electric's SD9354 Fusible Bus Plug Assembly is a 200-amp, 240-volt fusible plug-in unit designed for use with Square D busway systems, delivering a robust plug-in interface that carries load current between bus sections while housing protective fusible elements and enabling field-replaceable protection without disturbing adjacent sections. Listed as a fusible bus plug within the Square D SD family, the SD9354 is specified for 200 A at 240 V and is designed to mate with compatible busway components to create modular, protected distribution points within a larger bus run, supporting quick reconfiguration as facility needs evolve. In typical industrial power distributions, such bus plugs enable sectionalized maintenance and fault isolation without removing entire sections of the busway, allowing technicians to service a downstream feeder or fuse bank while the upstream section remains energized, depending on system design and fuse coordination. As part of Schneider Electric's broader Square D busway accessory ecosystem, the SD9354 integrates with matching bus sections, protective fuses, and mounting hardware to maintain consistent electrical characteristics and safe operation in high-density distribution networks across manufacturing plants, data centers, healthcare facilities, and other commercial environments.
