The Schneider Electric A9XPP612 is an Acti9 comb busbar, 1L+N configuration, 9 mm pitch between phase and neutral, spanning 12 modules (18 mm per way). It carries a rated operational current of 63 A at 40 °C, with a rated insulation voltage of 400 V AC per IEC 61439-1 and a rated impulse withstand voltage of 4 kV. This is the cuttable busbar for distributing power across a row of miniature circuit breakers or RCBOs in a consumer unit or sub-distribution board — the 12-way length covers a full row in a typical 12-module enclosure.
Mounts horizontally on top of tunnel-type terminals. The 9 mm pitch matches the standard spacing between phase and neutral terminals on Acti9 1P+N devices. Screw terminals on the busbar accept the outgoing conductors.
