It breaks fault currents up to 10 kA per EN 60898 and 20 kA per IEC 60947-2 — the higher figure matters when the upstream transformer or utility fault level exceeds 10 kA; the 20 kA rating gives you SCCR headroom without cascading upstream fuses. Tunnel terminals top and bottom accept copper conductors directly, no ferrule required.
Yes — both share the same 70 mm depth, tunnel terminals, and DIN-rail mounting. The 5SP4440-7 is 4-pole (4 modular width units) versus the 5SL4363-7's 3-pole (3 units), so the panel must have space for the extra pole. No busbar or wiring changes needed if the enclosure has the slot.
