How it sits against the B-curve sibling
The closest functional peer is the S204-B32 — same 4-pole, 32 A, 277 V, 10 kA interrupting, same DIN-rail footprint. The only difference is the trip curve: B curve (3–5× In) for resistive or general-purpose loads, D curve (10–20× In) for high-inrush inductive loads. If your panel was laid out for the B32, the D32 bolts into the same slot without rewiring — just make sure the load's inrush characteristic matches the D curve's wider magnetic trip band.
