The thermal derating curve is flat from 40 °C through 50 °C at the full 63 A, then drops to 60.48 A at 55 °C and 56.7 A at 70 °C. The integrated auxiliary trip uses the 3VA9608-0BB11 accessory. No communication function, no phase failure detection — this is a straightforward thermal-magnetic line protection device, not a smart breaker. The 3VA1163-5EF36-0BA0 measures 70 mm deep, 76.2 mm wide, and 130 mm tall. Depth of 70 mm leaves room behind a 200 mm deep enclosure for wiring and the UVR coil.","metaTitle":"Siemens 3VA1163-5EF36-0BA0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1163-5EF36-0BA0 molded case circuit breaker, 63 A rated, 3-pole, 187 kA breaking at 240 V.
