The Schneider Electric A9D02616 is an Acti9 iDPN Vigi residual-current circuit breaker with overcurrent protection (RCBO), combining a 16 A thermal-magnetic trip unit with integrated 10 mA earth-leakage protection in a single 1P+N module. It clips onto a DIN rail, occupies 4 x 9 mm pitches (36 mm wide), and is rated for 6000 A Icn at 230...240 V AC 50 Hz per EN/IEC 61009-2-1.
The 10 mA earth-leakage sensitivity is the standout spec on this part — most RCBOs in this form factor are 30 mA. That 10 mA threshold is typically specified for circuits where a lower fault current must be detected: wet locations, medical equipment in patient areas, or circuits supplying hand-held tools where the body path to ground is low impedance.
