The 3-pole footprint is standard for a three-phase branch circuit; the S800S series uses a modular width of 3 × 18 mm per pole, so this unit occupies 54 mm of rail space. Wire termination accepts up to 35 mm² conductor for the line and load sides — sized for the 32 A rating with headroom on the lug capacity.
The S803S-C32 is rated 32 A with a Trip Curve C characteristic (magnetic trip between 5× and 10× In).
Both are 3-pole DIN-rail MCBs from the same S800S family with the same 50 kA interrupting rating at 230 VAC, so the mechanical footprint and bus-bar pitch are identical. The difference is the trip curve — Curve C (5–10× In) on the C32 versus Curve D (10–20× In) on the D63 — and the current rating (32 A vs 63 A). If the branch circuit is sized for 32 A and the load doesn't need the higher inrush tolerance of Curve D, the C32 is a direct mechanical swap.
