Siemens 3VA1216-5EF32-0HA0 — 160 A SENTRON MCCB with TM240 release and shunt trip
Breaking capacity is specified at multiple voltage levels: 187 kA at 240 V AC, 121 kA at 415 V AC, 36 kA at 440 V AC, and 17 kA at 690 V AC. Current rating holds at 160 A from 40 °C through 50 °C, then derates linearly to 142.4 A at 70 °C. The thermal curve matters for panel builders packing breakers into a confined enclosure — if the ambient inside the panel runs above 50 °C, the effective continuous current drops. Plan the load accordingly.
Dimensions: 105 mm wide, 158 mm high, 70 mm deep. No auxiliary contact version is fitted as standard; the only integrated auxiliary is the shunt trip. If the BOM calls for any of those, this variant is the wrong pick — the shunt trip alone covers remote tripping via a control signal.
