The 15 kA Icu (ultimate breaking capacity) at 230/400 V tells you this breaker can safely interrupt a fault current up to 15,000 A without welding its contacts or failing catastrophically — critical for panel coordination where the upstream transformer can deliver that kind of fault energy. The 1P+N format switches the line conductor and disconnects the neutral, common in single-phase final subcircuits where you want full isolation. D6 curve: 6 A thermal rating with the magnetic trip set for 60–120 A, so it holds through motor start currents but trips fast on a bolted fault. ## Panel integration The 1-pole-width footprint (about 18 mm per pole) keeps panel density high.","metaTitle":"Siemens 5SY4506-8CV MCB, 1P+N D6, 15kA Icu 230/400V","metaDescription":"Siemens 5SY4506-8CV miniature circuit breaker, 1P+N, D6 curve, 15kA interrupting capacity at 230/400V.
