This breaker is rated 10 kA per EN 60898 and 35 kA per IEC 60947-2 at 400 V AC. For DC circuits, it handles 15 kA per IEC 60947-2 up to 72 V — useful for battery-backed control circuits or DC bus protection.
Touch protection is built in, reducing the risk of accidental contact during panel work.

It is rated 10 kA per EN 60898 and 35 kA per IEC 60947-2 at 400 V AC. For DC circuits, it handles 15 kA per IEC 60947-2 up to 72 V.
The combined terminals accept solid or stranded conductors from 0.75 mm² up to 35 mm².
Both are 1-pole SENTRON MCBs with the same 18 mm width and DIN-rail mounting, so the footprint is identical. However, the 5SY3132-6 has a different current rating and tripping characteristic — verify the BOM's required rating before swapping. The terminal range (0.75...35 mm²) is the same, so no rewiring is needed if the rating matches.
