It breaks fault currents up to 30 kA at 400 V AC per IEC 60947-2 — enough to handle high-fault utility feeds without cascading upstream breakers. Neutral conductor switching is included (3P+N), so it clears all live conductors in a single fault event. Occupies 4 modular width units (72 mm wide) with a depth of 76 mm (70 mm installation depth behind the panel). Mounts in any position — no derating for horizontal or vertical orientation. Terminal design allows combined top and bottom feed — useful for busbar looping or daisy-chaining downstream loads without extra junction blocks. Current-production part. No end-of-life notification or successor identified.","metaTitle":"Siemens 5SY8620-7 SENTRON MCB, 20 A C-Curve 4P 30 kA","metaDescription":"Siemens 5SY8620-7 SENTRON miniature circuit breaker, 20 A rated, C characteristic, 4-pole (3P+N), 30 kA breaking capacity at 400 V AC per IEC 60947-2.
