The Schneider Electric A9XPF524 is an Acti9 comb busbar rated 100 A at 40 °C and 415 V AC, laid out as 3L+N balanced with Vigi taps at 40/63 A. It spans 24 modules at an 18 mm pitch — 432 mm total width — and mounts horizontally on tunnel-type terminals inside a panel. The 415 V AC operational voltage and 500 V AC rated insulation voltage (per IEC 61439-2) give it headroom for 400 V three-phase networks common in European industrial panels.
The busbar is cuttable to length and accepts tooth-type connectors. The 18 mm pitch matches standard Acti9 modular devices; the 24-module length fits a 432 mm DIN-rail span. IP20 with end-pieces and tooth covers keeps fingers off live copper inside the enclosure. The 960 °C glow-wire test (IEC 60695-2-1) confirms the insulation won't propagate a fire under fault conditions.
