The part is designed for railway applications and mechanical engineering/industry environments, with an IP20 rating (with connected conductors) and a wide ambient temperature range of -40 to +70 °C. The B-curve trips between 3 and 5 times rated current — so at 30 to 50 A — making it suitable for resistive or general-purpose loads where inrush is modest. The 10 kA breaking capacity at 400 V AC is the standard for most building distribution boards; it confirms the MCB can clear a bolted fault on a 10 kA prospective short-circuit current without rupturing. The 3-pole configuration switches all three phases simultaneously, which is required for three-phase final circuits. Conductor termination accepts solid or stranded wire from 0.75 to 35 mm², with a tightening torque of 2.5 to 3.5 N·m — that range covers standard panel wiring up to 35 mm² for a 10 A circuit. The MCB mounts via a quick assembly system — the standard DIN-rail clip for SENTRON devices. It occupies 3 width units at 54 mm wide, with a depth of 76 mm and an installation depth of 70 mm. The sealable design supports lockout/tagout procedures.","metaTitle":"Siemens 5SY4310-6CC11 SENTRON MCB, 3P B-Curve 10A 10kA","metaDescription":"Siemens SENTRON 5SY4310-6CC11 miniature circuit breaker, 3-pole, B-curve, 10 A rated, 10 kA breaking capacity at 400 V AC.
