The Siemens 3VA2110-0HL32-0AA0 is a SENTRON molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies panel thermal budgeting in a crowded enclosure. Breaking capacity hits 440 kA at 415 V AC and 187 kA at 690 V AC, so this breaker handles high-fault scenarios common on large transformer secondaries or industrial mains without cascading upstream.
The 3VA2110-0HL32-0AA0 measures 105 mm wide, 181 mm high, and 86 mm deep — it drops into standard SENTRON 3VA mounting footprints. Three-pole construction with no undervoltage release or shunt trip on this variant; the ETU320 handles all protection logic internally. Power loss is 7.7 W maximum at rated current — negligible for most enclosures but worth noting if you are packing multiple breakers into a sealed, non-ventilated cabinet.
