It's a line-protection breaker — meaning it's sized for feeder and distribution circuits, not motor-starting duty where a separate overload relay would be needed. Breaking capacity is the headline here: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. Those numbers tell you this breaker can sit upstream of a high-fault panel without needing a current-limiting fuse ahead of it — the 121 kA at 240 V covers most North American service-entrance scenarios, and the 75.6 kA at 415 V handles European industrial distribution. Footprint is 130 mm high, 76.2 mm wide, 70 mm deep — standard 3-pole MCCB size that fits most DIN-rail or panel-mount enclosures. Above that it derates: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, 56.7 A at 70 °C.","metaTitle":"Siemens 3VA1163-4EF32-0JH0 SENTRON MCCB, 63 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1163-4EF32-0JH0 molded case circuit breaker. 63 A rated, 3-pole, TM240 release, 121 kA breaking at 240 V.
