The 63 A frame carries the same interrupting ratings whether the panel ambient sits at 40 °C or 70 °C (–), so you don't lose headroom in a hot enclosure. ## Field-service note The 5.4 W maximum power loss is low enough that you don't need forced ventilation around it in a typical panel. Mechanical endurance is 20,000 operations — that's a lifetime of routine switching, not a daily cycling device. If you're swapping one in on site, the 181 mm height clears most standard distribution sections. No special tools needed beyond a Torx driver for the line and load lugs.","metaTitle":"Siemens 3VA2063-5KQ32-0AA0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2063-5KQ32-0AA0 molded case circuit breaker, 63 A continuous, 187 kA breaking at 240 V, ETU860 electronic trip.
