Product Application
Whether feeding a high-rise basement, a wind-tower platform, or a metro service gallery, the XGN15-12 RMU drops straight into 630–1250 A sandwich busway—no transition box, no copper work. The slim 0.27 m² footprint slips through narrow shafts, while F-type panels take busway mains and F+R units protect each tap-off box, clearing faults locally so the rest of the line stays live. City grids, data halls, hospitals, rail tunnels—anywhere space is tight and downtime costs dear—this RMU makes busway expansion as simple as “plug, latch, energize.” It’s a compact, busway-ready RMU that turns dense urban distribution into fast, predictable installation.
