Full 63 A rating holds through 50 °C ambient. At 55 °C it derates to 60.48 A, at 60 °C to 59.22 A, at 65 °C to 57.96 A, and at 70 °C to 56.7 A. That's a shallow derating curve — you don't lose much headroom in a warm enclosure. ## Integrated undervoltage release — no auxiliary contacts There are no auxiliary contacts on this version, so if you need status feedback to a PLC, plan for a separate auxiliary switch block.","metaTitle":"Siemens 3VA1163-5EF32-0CA0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1163-5EF32-0CA0 molded case circuit breaker, 63 A rated, 187 kA breaking at 240 V.
