The Siemens SENTRON 3VA2163-0HL36-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current across the full ambient range from 40 °C through 70 °C — no derating needed up to that ceiling.
The 3VA2163-0HL36-0AA0 measures 105 mm wide by 181 mm tall by 86 mm deep — a standard 3-pole MCCB footprint that drops into SENTRON mounting bases and most DIN-rail adapter plates without re-drilling gland plates. Front face carries IP40 protection, so it's fine in a ventilated enclosure; no washdown rating. Power loss is 3.1 W maximum — negligible for thermal budgeting inside a crowded panel.
