It is a line-protection device, meaning it guards cables and busbars against overload and short-circuit — not a motor-protective breaker with integrated phase-loss detection. The interrupting ratings are substantial: 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V, so it can handle high-fault-current scenarios like large transformer secondaries or main feeders in industrial distribution. ## Derating and thermal reality Above that, it derates linearly: 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. Storage range is wider: -40 °C to 80 °C. ## Physical fit and integration The auxiliary trip is a separate order code (3VA9608-0BB25) if you need shunt or UVR wiring. No communication module or ground-fault monitoring is built in; this is a straight thermal-magnetic breaker with a UVR coil.","metaTitle":"Siemens SENTRON 3VA1163-4EF32-0DC0 MCCB, 63 A, 3-pole, TM240","metaDescription":"Siemens SENTRON 3VA1163-4EF32-0DC0 molded case circuit breaker, 63 A rated continuous current, 3-pole, TM240 overcurrent release, 121 kA at 240 V.
