It breaks fault currents up to 3 kA per EN 60898 at 400 V AC, 50 Hz. Overvoltage category 3 and energy limiting class 3 place it in standard distribution panel duty. Occupies 3 width units (roughly 54 mm) on a DIN rail, with a 55 mm installation depth — fits standard 63 A distribution boards without crowding. IP20 finger-safe terminals; no neutral pole switching (3P, not 3P+N). Rated AC/DC voltage, so it can also switch DC control circuits within its breaking capacity, though the 3 kA rating is per EN 60898 at AC.","metaTitle":"Siemens SENTRON 5SQ2370-0KA15 MCB, 3-Pole, C-Curve, 15 A, 3","metaDescription":"Siemens SENTRON 5SQ2370-0KA15 miniature circuit breaker, 3-pole, C tripping characteristic, 15 A rated current, 3 kA breaking capacity per EN 60898, 400 V AC, IP20.
