This one switches the neutral conductor (3P+N) so you get full isolation on all poles, not just the phases. Breaking capacity is dual-rated: 6 kA per IEC/EN 60898-1 for residential/commercial distribution, and 30 kA per IEC 60947-2 for industrial panel duty. That 30 kA figure at 400 V AC means it can interrupt a fault up to 30 kA without welding contacts or cascading upstream — a real advantage when you're coordinating selectivity in a panel fed by a high-capacity transformer. Also carries a 15 kA DC rating at 60 V per IEC 60947-2, and 5 kA per UL 1077/CSA. Rated for 400 V AC (440 V max in multi- or single-phase operation), 50/60 Hz. Operating temperature range from -40 °C to 75 °C, with humidity derating above 55 °C. Pollution degree 3, overvoltage category III — suitable for fixed installations in industrial environments where conductive pollution or condensation is present. Mount in any position.","metaTitle":"Siemens 5SY6606-6 SENTRON MCB, 4P, B-Curve, 6kA/30kA","metaDescription":"Siemens 5SY6606-6 SENTRON miniature circuit breaker, 4-pole (3P+N), B-curve, 6 kA per EN 60898, 30 kA per IEC 60947-2.
