The C-curve means it holds through motor inrush up to about 5–10× rated current — fine for general-purpose lighting and small motor branch circuits, not for high-inrush transformer loads where a D-curve would be needed.
The IP20 rating applies with conductors connected — fine inside a closed enclosure, not for wet locations. Mounting position is unrestricted, so it can go sideways or upside-down in a tight gland plate layout without derating.
It is rated 6 kA per both EN 60898 and IEC 60947-2 at 400 V AC. That covers typical residential and light commercial fault levels; for higher SCCR requirements (10 kA or above), look at the 5SL4363-7 sibling.

Yes — both share the same 54 mm width (3 MW), 76 mm depth, 70 mm installation depth, and DIN-rail mounting. The 5SL4363-7 carries a 10 kA breaking capacity versus 6 kA on this part, but the physical footprint is identical, so no rewiring or panel modification is needed.
