The Schneider Electric A9D67416 is an Acti9 iC60 RCBO — a combined overcurrent and residual-current device in a single 4-pole module, rated 16 A with a C-curve magnetic trip (5…10 x In) and integrated 30 mA earth-leakage protection. The 6 kA breaking capacity (Icu at 380…415 V AC per EN/IEC 60947-2) and 6000 A Icn per EN/IEC 61009-2-1 clear a fault at that level on a three-phase outgoer. The thermal-magnetic trip unit handles the 16 A continuous load; the 30 mA residual-current element protects personnel against earth faults — common for socket-outlet or wet-area circuits in commercial and light-industrial distribution boards.
Overvoltage category III per IEC 60364, meaning it is rated for fixed-installation distribution boards with transient overvoltages up to 4 kV. IP40 in distribution enclosure (IP20 naked) per IEC 60529 — standard for panel-mounted breakers; not rated for wet washdown environments.
