The Siemens 3VA2010-6HN36-0HH0 is a SENTRON 3VA2 molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C up to 70 °C — no derating needed in a warm panel. Breaking capacity is the headline number here: 242 kA at 240 V AC, 187 kA at 415 V, and still 121 kA at 500 V. That puts it in the high-interrupting category — it clears a fault without the arc re-striking, and it gives you selectivity headroom downstream.
Power loss is 13.5 W maximum. Account for it in the thermal budget.
