The 3VA1110-4GE46-0AA0: Breaking capacity climbs with system voltage: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and holds 11.9 kA all the way up to 690 V. That gives you selectivity headroom downstream without over-speccing the main.
Rated 100 A up to 50 °C ambient; above that it steps down: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, 91 A at 70 °C. Footprint is 101.6 mm wide by 130 mm tall by 70 mm deep — a standard 4-pole MCCB slot on the DIN rail or panel-mount plate.
The 100 % N-conductor protection design means the neutral pole is fully rated — not a switched-neutral or reduced-section neutral. That's important for panels feeding non-linear loads or where harmonic currents might load the neutral. Compliance documentation (RoHS, REACH, IEC) is standard with the Siemens SENTRON family.
