Rated operating voltage is 400 V AC (single- or multi-phase) and 60 V DC, with a DC breaking capacity of 15 kA per IEC 60947-2. The 2-pole design switches both live conductors — no neutral switching. Environmental range covers -40 °C to +75 °C, with humidity derating above 55 °C. IP20 with connected conductors — fine inside a sealed panel; not for washdown zones.","metaTitle":"Siemens SENTRON 5SY4201-7KK11 MCB, 2P, C-curve, 10 kA","metaDescription":"Siemens SENTRON 5SY4201-7KK11 miniature circuit breaker, 2-pole, C characteristic, 10 kA per EN 60898, 35 kA per IEC 60947-2.
