The interrupting ratings span the common industrial voltages: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. At 415 V, that 154 kA covers high-fault scenarios downstream of large transformers — typical for a main breaker in a 400 V panel feeding motor control centers or secondary distribution.
The 3VA1112-6EF32-0AB0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole footprint that fits standard Siemens SENTRON mounting plates and panel cutouts. Two auxiliary switches (HP type) are built in, providing status feedback for remote monitoring or interlocking without adding external contact blocks. No undervoltage release or shunt trip is included — if you need those, they're available as add-on accessories in the 3VA family. The current derating curve starts at 55 °C (122 A), dropping to 114 A at 70 °C — account for that if the breaker sits near heat sources or in a non-ventilated enclosure.
