It breaks fault currents up to 3 kA per EN 60898 — enough for most residential and light commercial final circuits, but not for high-fault industrial mains. The C-curve means it trips between 5× and 10× rated current, so it handles motor inrush and transformer energisation without nuisance tripping on standard lighting or receptacle loads. ## Mounting and integration Occupies 3 width units on a DIN rail. Installation depth is 55 mm — fits standard distribution boards and sub-panels without bottoming out on the enclosure door. No neutral conductor switching (the 3-pole version handles line-only). IP20 finger-safe terminals suit enclosed panels; not rated for washdown or outdoor exposure.","metaTitle":"SENTRON 5SQ2370-0KA13 MCB, 3-Pole, C-Curve, 13A, 3kA, 400V A","metaDescription":"SENTRON 5SQ2370-0KA13 miniature circuit breaker, 3-pole, C tripping characteristic, 13 A rated current, 3 kA breaking capacity at 400 V AC per EN 60898.
