Thermal derating starts above 50 °C: still holds 63 A at 50 °C, drops to 60.6 A at 55 °C, and 53.6 A at 70 °C. The 4 W maximum power loss is low enough that ventilation in a standard enclosure handles it without forced air. The front face carries an IP40 protection class, so it's fine for dry indoor enclosures but not washdown zones. If you need remote status or shunt trip, you'll add those externally.","metaTitle":"Siemens 3VA2163-7HN32-0AF0 SENTRON MCCB, 63 A, 3-Pole, ETU35","metaDescription":"Siemens SENTRON 3VA2163-7HN32-0AF0 molded case circuit breaker, 63 A, 3-pole, ETU350 release.
