Rated at 6 A with a B tripping characteristic, this MCB trips instantaneously at 3 to 5 times rated current — so between 18 A and 30 A magnetic trip. That's typical for sub-distribution boards downstream of a main breaker with higher interrupting rating. The 55 mm installation depth and 2 width units mean it occupies two 18 mm DIN-rail modules — a compact footprint that leaves room for additional circuits in a crowded enclosure. IP20 finger-safe protection is the norm for panel-mounted breakers; no special sealing required inside the cabinet.
Peer comparison — 5SQ2570-2YA04 vs this 5SQ2560-0KA06
The closest functional sibling is the 5SQ2570-2YA04, which shares the same 2-pole 5SQ platform, 55 mm depth, IP20, and 3 kA breaking capacity. The difference is in the trip curve and voltage: the 5SQ2570-2YA04 is a C-curve (magnetic trip at 5–10× In) rated 4 A at 400 V AC, while this 5SQ2560-0KA06 is a B-curve at 6 A and 240 V AC. If your panel was specified around the 5SQ2570-2YA04, this unit will not drop in without rewiring — the voltage rating and current differ, and the neutral switching configuration (1P+N vs 2P) may not match the circuit design. For a like-for-like replacement, stick with the original order code.
