At 690 V it still clears 17 kA, which matters for industrial loads fed from step-up transformers. It's a pure line-protection device: no bells, no remote status. The TM240 release means the thermal element is calibrated for 240 A frame, but the breaker itself is rated 63 A; the magnetic pickup is fixed and non-adjustable on this variant. Thermal derating is modest: full 63 A holds from 40 °C through 50 °C, 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. ## Panel fit and lifecycle Mechanical endurance is rated at 15,000 operations — typical for a 63 A MCCB in distribution duty, not a motor-switching role. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits Siemens 3VA busbar adapters and panel cutouts. No phase-failure detection, no communication function, no voltage trigger beyond the shunt trip — this is a straightforward thermal-magnetic breaker with a remote trip coil for emergency-off or undervoltage schemes wired externally.","metaTitle":"Siemens 3VA1163-6EF32-0JA0 SENTRON MCCB, 63 A, 3-pole, 220 k","metaDescription":"Siemens 3VA1163-6EF32-0JA0 SENTRON molded case circuit breaker, 63 A rated, 3-pole, 220 kA breaking at 240 V.
