The C-curve (energy limiting class 3) means it trips between 5 and 10 times rated current — suited for protecting general-purpose circuits with moderate inrush, like lighting banks or small transformer loads. The 3 kA SCCR at 400 V AC is the maximum fault current it can safely interrupt under EN 60898; verify it coordinates with the upstream protective device in your panel. EN 60898 certifies its performance for household and similar installations. ## Panel integration The 5SQ2370-0KA01 occupies 3 width units on a DIN rail, with an installation depth of 55 mm. IP20 finger-safe terminals suit enclosed panel mounting.","metaTitle":"SENTRON 5SQ2370-0KA01 MCB, 3-pole C 1A 400V AC 3kA","metaDescription":"SENTRON 5SQ2370-0KA01 miniature circuit breaker, 3-pole, C-curve, 1A, 400V AC, 3kA breaking capacity per EN 60898.
