Rated 20 A with a C curve (magnetic trip between 5 and 10 times In), it handles the inrush of motor or lighting loads without nuisance tripping, while the 6 kA breaking capacity at 380–415 V AC meets the standard for final distribution circuits in commercial and light industrial panels. The 300 mA earth-leakage sensitivity is set for equipment protection rather than personnel shock protection — it catches insulation faults and ground leaks that could degrade wiring or start a fire, but does not meet the 30 mA threshold required for socket-outlet circuits in most residential codes. In a distribution board serving fixed equipment (pumps, compressors, lighting), this is the right choice to avoid nuisance trips from accumulated leakage on long cable runs. The C curve means the magnetic release operates between 5 and 10 times the rated current — 100 to 200 A for this 20 A unit. That suits loads with a moderate inrush, such as small motors, contactor coils, or fluorescent lighting banks. For highly inductive loads or large transformers, a D curve would be needed; for purely resistive loads, a B curve would suffice. In a panel with sensitive electronics, this is a meaningful advantage over a class 1 or 2 device. The 90 mm width (10 x 9 mm pitches) occupies a standard DIN-rail slot. The clip-on mounting and tunnel terminals accepting up to 16 mm² rigid wire make for straightforward panel integration. IP20 on the body, IP40 inside the modular enclosure — suitable for dry indoor panels only.","metaTitle":"Schneider Electric A9D41720 Acti9 DPN Vigi, 20 A, 30 mA RCBO","metaDescription":"Schneider Electric A9D41720 Acti9 DPN Vigi RCBO, 20 A rated, 300 mA earth leakage, curve C, 6 kA breaking capacity, 3P+N, DIN rail mount.
