It switches the neutral conductor (3P+N), so it fits sub-distribution boards where a switched neutral is required for isolation or selectivity. Rated for overvoltage category 3 and energy limiting class 3, it provides adequate surge withstand and fault-energy limitation for fixed-installation sub-circuits.","metaTitle":"SENTRON 5SQ2670-0KA50 MCB, 4-pole C 50A, 3kA","metaDescription":"SENTRON 5SQ2670-0KA50 miniature circuit breaker, 4-pole (3P+N), C-curve, 50 A, 3 kA per EN 60898/IEC 60947-2, 400 V AC, 50 Hz, IP20.
