The D curve (10–20× In) is the key selection parameter here: it's sized for loads with high inrush, typically motor starters, transformers, or discharge lighting. At 20 A, expect this to hold a 15 A motor full-load current without nuisance tripping during start-up. The thermal derating table is worth noting: at 40 °C ambient the continuous rating drops to 18.8 A, and at 50 °C to 17.52 A; if the panel runs hot, size up one frame. Depth of 76 mm (70 mm installation depth) clears most shallow enclosures. Any mounting position is allowed, which simplifies layout in crowded cabinets.","metaTitle":"Siemens 5SY4620-8CC SENTRON MCB, 20 A, D Curve, 10 kA","metaDescription":"Siemens 5SY4620-8CC SENTRON miniature circuit breaker, 20 A rated, D tripping characteristic, 10 kA breaking capacity per EN 60898, 4-pole 3P+N.
