Occupies 2 width units on a standard DIN rail, with 55 mm installation depth. Overvoltage category 3 and energy limiting class 3 place it in the standard residential and light commercial coordination tier. ## Drop-in vs sibling ratings Same physical footprint, terminal layout, and DIN-rail clip as the 5SQ2570-2YA04 (4 A C-curve) and 5SQ2270-2YA04 / 5SQ2270-2YA03 (3 A C-curve). All share 2-pole 1P+N construction, 55 mm depth, IP20, and 3 kA breaking capacity. The only difference is the thermal-magnetic trip rating — a panel wired for a lower-rated sibling can accept the 50 A unit without rewiring, provided the downstream conductors and load are sized for 50 A.","metaTitle":"SENTRON 5SQ2570-2YA50 MCB, 2P C 50A, 3kA, 400V AC","metaDescription":"SENTRON 5SQ2570-2YA50 miniature circuit breaker, 2-pole, C-curve, 50 A rated current, 3 kA breaking capacity per EN 60898, 400 V AC, 50 Hz.
