Siemens SENTRON 3VA1110-6MH36-0BA0 — 100 A MCCB with Undervoltage Release
Breaking capacity is the headline spec here: 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V.
Rated 100 A from 40 °C through 50 °C, then derates: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. Maximum power loss is 27.5 W. Panel builders should account for that heat dissipation in enclosure sizing, especially when grouping multiple breakers.
The 70 mm depth is relatively shallow for a 100 A MCCB with this breaking capacity, which helps in tight enclosures. Width at 76.2 mm (3 inches) is standard for a 3-pole frame. No trip indicator or communication function on this variant — it's a straightforward thermal-magnetic breaker with undervoltage release.
