The Schneider Electric A9D35616 is an Acti9 iDPN Vigi residual-current circuit breaker with overcurrent protection (RCBO), combining a 16 A thermal-magnetic trip unit (C-curve, 5...10 x In magnetic trip) and a 30 mA earth-leakage module 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 distribution outgoing circuits on 230...240 V AC 50 Hz networks.
The 30 mA earth-leakage sensitivity provides personnel protection (30 mA is the standard threshold for shock protection per IEC 60364). Breaking capacity is 4500 A Icn at 230...240 V AC, which is the standard domestic/commercial level in many markets; if your fault current exceeds that, you need a higher-rated upstream device.
Neutral is on the left. Terminals accept 1...16 mm² rigid or 1...10 mm² flexible (with or without ferrule); strip length 15 mm, tightening torque 2 N.m. IP20 finger-safe on the front, IP40 inside a modular enclosure.
