Breaking capacity is rated 6 kA per EN 60898 and 15 kA per IEC 60947-2, with a separate 5 kA rating under UL 1077 / CSA C22.2 No. 235. For DC circuits, the maximum rated voltage is 72 V with a 15 kA interrupting rating per IEC 60947-2. ## Environmental and compliance documentation IP20 protection applies with connected conductors, meaning finger-safe terminals but no ingress protection against water or dust. Touch protection is built in. The ambient operating range spans -40 °C to 75 °C, with humidity derating above 55 °C (95% RH up to 55 °C, 55% RH up to 70 °C, 35% RH up to 75 °C). Overvoltage category III suits fixed-installation distribution panels. The part is sealable for tamper-evident applications. ## Integration notes for panel builders and commissioning engineers The 4-pole (4P) design occupies 4 width units (72 mm total width). Combined terminals at both top and bottom simplify daisy-chaining busbars. Neutral conductor switching is not integrated — the breaker switches all four poles as phase conductors. The supply cord position is unrestricted. For selectivity studies, coordinate the 15 kA (IEC 60947-2) rating with downstream devices; the 6 kA (EN 60898) rating governs the non-industrial branch circuit.","metaTitle":"Siemens 5SY6410-8 SENTRON MCB, 4P, 10 A, D Curve, 6 kA","metaDescription":"Siemens 5SY6410-8 SENTRON 4-pole MCB, 10 A rated, D tripping characteristic, 6 kA (EN 60898) / 15 kA (IEC 60947-2) breaking capacity.
