Overvoltage category 3 and energy limiting class 3 mean it coordinates downstream and limits let-through energy in a fault. IP20 finger-safe terminals suit enclosed panel mounting; no neutral conductor switching on this 3P variant. ## Selectivity & coordination note In a typical residential or light commercial distribution board fed by a higher-rated upstream MCCB or NH fuse, this MCB provides full discrimination up to its rating. The C-curve ensures the magnetic trip operates between 50 A and 100 A (5–10× 10 A) — fast enough to clear a bolted fault before the upstream device reaches its time-current threshold, provided the upstream overcurrent device is sized with a ratio of at least 2:1 on the thermal side.","metaTitle":"Siemens SENTRON 5SQ2370-2YA10 Miniature Circuit Breaker, 3-p","metaDescription":"Siemens SENTRON 5SQ2370-2YA10 miniature circuit breaker. 3-pole, C-curve, 10 A, 3 kA breaking capacity at 400 V AC.
