SENTRON 3VA2 MCCB — 63 A, 3-Pole Line Protection
Its 187 kA breaking capacity at 240 V AC handles high-fault utility feeds; at 415 V and 440 V it still clears 121 kA, dropping to 75.6 kA at 500 V and 3.7 kA at 690 V. That puts it squarely in the high-interrupting class for industrial distribution, not a light-duty branch breaker. Communication function is onboard, so it can feed status back to a PLC or BMS without a separate interface module.
