That SCCR headroom means it can sit upstream of a high-fault panel without cascading — a common requirement for industrial switchboards and motor control centers. Thermal derating is flat from 40 °C to 50 °C (still 63 A), then drops to 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. It ships with 1 auxiliary switch + 1 trip alarm switch (HQ version) integrated, so you get status feedback and a separate alarm contact without adding an external module. The 3VA1163-4EF32-0AF0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. That 76.2 mm width (3 inches) is the standard 3-pole MCCB footprint — it drops into a panel cutout sized for a 3-pole SENTRON 3VA frame without modification.","metaTitle":"Siemens 3VA1163-4EF32-0AF0 SENTRON MCCB, 63 A, 3-Pole, TM240","metaDescription":"Siemens 3VA1163-4EF32-0AF0 SENTRON molded case circuit breaker, 63 A, 3-pole, TM240 release, 121 kA at 240 V.
