The Schneider Electric A9XPH612 is an Acti9 comb busbar — a cuttable 12-way bar for distributing 1L+N circuits at 9 mm pitch. It carries 80 A at 40 °C (rated operational current per IEC 61439-1), so it feeds a full row of 18 mm MCBs or RCBOs without a separate jumper.
Mounts horizontally at the bottom of tunnel-type terminals. The tooth connector engages the busbar risers of compatible Acti9 devices — no separate screw-clamp needed on each pole. IP20 with the supplied end-pieces and tooth covers, so it's safe for finger-probe access inside a closed panel. Cuttable to length: score the 18 mm module marks and snap off what you don't need.
