The Schneider Electric A9XPM512 is a Linergy FH comb busbar — a 4-pole, 12-module, 100 A connection accessory for the Acti 9 MiniLine distribution system. It mounts horizontally and uses a tooth-style connector to distribute power across N N L2 N L3 in a balanced 4P layout. The 220 mm width and 36 mm distance between ways match the standard DIN-rail pitch, so it slots directly into a panel without extra adaptors.
This busbar is obsolete per Schneider's lifecycle status.
