SENTRON 5SQ2570-2YA50 — 2-pole C-curve MCB, 50 A, 3 kA
It carries a C tripping characteristic at 50 A rated current, breaking capacity rated 3 kA per EN 60898 at 400 V AC, 50 Hz.
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.
