Rated breaking capacity hits 10 kA per EN 60898 at 400 V AC, which covers the fault-current duty of most 400 V distribution boards in mechanical engineering and factory-floor environments. The B-curve trips between 3 and 5 times rated current, so it's a good fit for resistive or lightly inductive loads where you want fast clearing on a short-circuit but don't need the inrush headroom of a C or D curve. ## Sourcing and lifecycle For volume or blanket-order inquiries, submit an RFQ. The part is a standard SENTRON catalog item, so lead times are generally consistent with Siemens distribution channels.","metaTitle":"Siemens 5SY4402-6CC11 SENTRON MCB, 4P, B-Curve, 10 kA, 400 V","metaDescription":"Siemens SENTRON 5SY4402-6CC11 miniature circuit breaker. 4-pole, B characteristic, 10 kA breaking capacity per EN 60898.
