That SCCR headroom is what makes it a fit for main or feeder duty in a panel with a large transformer behind it. The 'starter protection' product version means the TM120M release curve is coordinated for motor-starting inrush — it rides through the 6–8× FLA spike without nuisance tripping, then clears a locked-rotor or bolted fault. The 75 W operating power at AC-3 / 400 V confirms it is sized for a motor load, not just resistive heating. If your BOM calls for remote trip or earth-leakage, you need a different variant in the 3VA family. The 200 A rating holds flat from 40 °C through 50 °C, then derates to 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C (–). In a sealed, non-ventilated enclosure at 50 °C ambient, you still get the full 200 A; above that, the continuous current drops. The 70 mm depth, 105 mm width, and 158 mm height (–) fit a standard MCCB slot in a SENTRON distribution panel or a generic DIN-rail enclosure with the appropriate mounting base. The 4 HQ auxiliary switches provide status feedback for PLC or SCADA; the HQ designation typically means high-rupturing-capacity contacts suitable for switching control transformer loads. The 4 HQ auxiliary switches are factory-integrated — no field-assembly of aux contacts needed.","metaTitle":"Siemens 3VA1220-5MH32-0AE0 SENTRON MCCB, 200 A, 3-Pole, Star","metaDescription":"Siemens SENTRON 3VA1220-5MH32-0AE0 molded case circuit breaker, 200 A continuous, 3-pole, TM120M release, 187 kA at 240 V.
