The Schneider Electric A9XPH416 is an Acti9 comb busbar — a 4-way (3L+N) connection accessory rated 100 A at 40 °C and 415 V AC, with an 18 mm connection pitch spanning 16 modules (288 mm total width). It distributes power from a single feed to multiple downstream devices in a panel, with the N L2 L3 marking and a 4 ways N + 3 L pole configuration per way.
The 100 A rating at 40 °C sets the continuous current limit for the busbar in a panel environment — derate above that ambient. The 415 V AC operational voltage matches standard three-phase distribution in many industrial and commercial installations. The 18 mm pitch and 16-module length mean it occupies 288 mm of DIN-rail width, fitting into a cuttable form factor that can be trimmed to the exact number of ways needed.
Mounts horizontally on DIN rail via the tooth-type connector. The busbar is insulated and accepts top or bottom feed on tunnel-type or double terminals. IP20 protection applies only when end-pieces and tooth covers are fitted — plan for those accessories if the panel requires finger-safe touch protection. The 960 °C glow-wire test (IEC 60695-2-1) confirms fire resistance for 30 seconds, relevant for panel certification to EN/IEC 61439-1.
