The Siemens SENTRON 3VA2010-5HN36-0DA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, with a 187 kA interrupting capacity at 240 VAC.
The interrupting rating drops as system voltage climbs: 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3 kA at 690 V. That 3 kA at 690 V is the number to watch if you're feeding a 690 V drive — it's still adequate for most downstream faults but confirms this MCCB is primarily sized for 240–500 V distribution where the high fault current matters.
Thermal performance and panel fit
Power loss maxes at 16 W, which is modest for a 100 A frame; ventilation in a standard enclosure handles it.
