The breaker holds its full 63 A rating up to 50 °C ambient, then derates linearly: 60.6375 A at 55 °C, 58.275 A at 60 °C, 55.9125 A at 65 °C, and 53.55 A at 70 °C. Maximum power dissipation is 6.5 W, so heat buildup in a sealed enclosure is manageable. The trip indicator is present, so a local flag shows whether the breaker opened on a fault vs. manual operation. The storage minimum matters for warehousing in unheated facilities — this breaker can sit in a -40 °C freezer warehouse without damage, but must be warmed before energizing to avoid condensation. Rated insulation voltage (Ui) is 800 V, which covers most 400/480 V systems with margin, and the 690 V breaking capacity of 5.25 kA is the low end — so on a 690 V system, verify the available fault current is under that threshold.","metaTitle":"Siemens 3VA2163-7HN32-0BH0 SENTRON MCCB, 63 A, 330 kA at 240","metaDescription":"Siemens 3VA2163-7HN32-0BH0 SENTRON molded case circuit breaker, 63 A rated current, 330 kA breaking capacity at 240 V, 3-pole, ETU350 release, undervoltage release.
