The A9D67313 is a 3-pole Acti9 iC60 RCBO — a combined overcurrent and residual-current device for AC distribution boards. The integrated earth-leakage protection trips at 30 mA sensitivity, which is the standard threshold for personal shock protection in IEC 60364 installations. The 6 kA breaking capacity (Icn at 380–415 V AC) is sufficient for most commercial and light industrial sub-distribution boards, but if your fault level at the board exceeds 6 kA you will need to coordinate upstream — the limitation class 1 rating means the device lets through enough energy that the upstream breaker must be sized to handle it. Mounting is clip-on to a standard DIN rail, occupying 6 x 9 mm pitches (54 mm width). The IP40 rating applies when enclosed in a distribution board; the device itself carries IP20. The toggle provides local signalling of ON, OFF, and fault-trip states, which saves time during commissioning and fault-finding.
It is rated for overvoltage category III per IEC 60364, which covers fixed-installation distribution boards.
