The A9D68620 is a Schneider Electric Acti9 iDPN Vigi residual-current circuit breaker with overcurrent protection (RCBO) in a 1P+N format, rated 20 A with a 6 kA breaking capacity at 230 V AC and 300 mA earth-leakage sensitivity, Curve B. The kit is complete — no separate RCD module or add-on needed; the earth-leakage protection is integrated into the same housing.
The 20 A rated current (In) and 6 kA Icn at 230 V AC define the maximum continuous load and the fault-clearing capability. The 300 mA earth-leakage sensitivity is set for protection against insulation faults, not direct human contact — that is a 30 mA threshold. The thermal-magnetic trip unit handles both overload (thermal bimetal) and short-circuit (solenoid) conditions. The 20,000-cycle electrical and mechanical endurance matches typical panel duty for a distribution outgoer.
Clip-on mounting on standard DIN rail (35 mm). The 9 mm connection pitch between phase and neutral matches the Acti9 busbar system. IP20 on the front, IP40 inside a modular enclosure — standard for indoor distribution boards.
Sourcing this order code
No minimum order quantity is imposed for this line. The part is fully specified for BOM inclusion — the 20 A, 6 kA, 300 mA, Curve B combination is a standard configuration for final-distribution RCBOs in commercial and light-industrial panels.
