The Schneider Electric A9D54613 is an Acti9 iDPN Vigi combined residual current circuit breaker with overcurrent protection (RCBO) — a single-module device that packs a 13 A thermal-magnetic MCB and a 30 mA earth-leakage trip into one 36 mm-wide DIN-rail housing. It is a 1P+N unit, meaning it switches the live conductor and monitors the neutral, with the neutral on the left side of the terminal layout. The B-curve characteristic (magnetic trip between 3 and 5 times In) makes it a natural fit for residential or light commercial final circuits where the inrush from connected loads is modest — think lighting, socket outlets, or general-purpose distribution.
The 4.5 kA Icn breaking capacity at 220–240 V AC conforms to EN/IEC 61009-2-1. That figure governs the maximum prospective fault current the device can safely interrupt. In a typical domestic or small commercial distribution board with a 6 kA or 10 kA upstream main breaker, this 4.5 kA rating means the RCBO is suitable for outgoing circuits where the fault level at the point of installation does not exceed that value — a coordination check the panel builder must confirm. The limitation class 3 rating (also per EN/IEC 61009-2-1) indicates good energy let-through performance, which helps with downstream selectivity. The integrated 30 mA residual current sensitivity covers the standard requirement for additional protection against direct contact in most IEC 60364 installations. The thermal-magnetic trip unit handles the overcurrent side — the thermal element protects against sustained overloads, the magnetic element against short-circuits. The device is rated for 20,000 electrical and 20,000 mechanical cycles, which is a solid endurance figure for a distribution RCBO. The 9 mm pitch between phase and neutral connections matches the Acti9 busbar system. The toggle provides local ON, OFF, and fault-trip indication.
