The Siemens SENTRON 3VA2110-5MN36-0HH0 is a 3-pole molded case circuit breaker (MCCB) rated at a flat 100 A across the full ambient range from 40 °C to 70 °C — no derating curve to chase. Designed specifically for motor protection, it includes phase failure detection and ships with a shunt trip (STL) release plus two auxiliary switches and one trip alarm switch HQ.
SCCR and selectivity planning
The interrupting ratings climb to 187 kA at 240 V and hold at 121 kA through 415–440 V, then step to 75.6 kA at 500 V and drop to 3.7 kA at 690 V. That 121 kA at 415 V gives solid headroom for most European industrial panels; the steep fall at 690 V means the breaker is effectively a backup device at that voltage — verify coordination with the upstream fuse or breaker if your line runs 690 V.
Integration notes
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without rework. The shunt trip (STL) and auxiliary switch complement (2 aux + 1 trip alarm HQ) are factory-fitted, so no field-add kit to order separately. Max power loss is 10 W; factor that into enclosure thermal calculations, especially in a sealed cabinet.
