The Siemens 3VA2110-6HN32-0AA0 is a SENTRON 3VA2 molded case circuit breaker (MCCB) built for line protection — the main disconnect and fault interrupter in a distribution panel or machine supply. 3-pole, rated 100 A continuous at 40 °C, and that 100 A holds all the way up to 70 °C without derating, so it fits high-ambient enclosures without oversizing. The interrupting ratings are the headline: 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V.
The 3-pole width is standard for a 100 A frame MCCB — fits a typical 600 mm wide panel with room for side-by-side mounting. Power loss is 10 W maximum, manageable for natural convection in a ventilated enclosure.
