The Schneider Electric A9D53613 is an Acti9 iDPN Vigi residual-current circuit breaker with overcurrent protection (RCBO) — one compact unit that combines a 13 A thermal-magnetic MCB and a 30 mA earth-leakage module. It protects a single-phase final subcircuit (1 pole + neutral) against overload, short-circuit, and earth faults, all in a 36 mm wide (4 x 9 mm pitch) clip-on module that snaps onto a DIN rail inside a distribution board.
Rated 13 A (In) with a C-curve magnetic trip (5 to 10 x In), so it's sized for general-purpose loads like lighting, socket outlets, and small appliances where inrush current is moderate — not for motor starting or transformer loads that need a D-curve. The 30 mA earth-leakage sensitivity (IΔn) meets the standard for personal protection in residential and commercial final circuits; it will trip on a fault current above 30 mA between live and earth. Breaking capacity is 6 kA Icn at 230…240 V AC, 50 Hz, conforming to EN/IEC 61009-2-1 — that's the maximum fault current the device can safely interrupt.
Clip-on mounting to DIN rail, 36 mm wide (4 x 9 mm pitches). Terminals accept 1…16 mm² rigid or 1…10 mm² flexible wire, with a stripping length of 15 mm and a tightening torque of 2 N·m. IP20 on the front, IP40 inside the modular enclosure.
