The Siemens 3VA2110-7MN32-0HA0 is a SENTRON molded case circuit breaker designed specifically for motor protection, with a continuous current rating of 100 A across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to that limit.
Three-pole construction, 105 mm wide by 181 mm tall by 86 mm deep — fits standard panel mounting footprints for 100 A frame MCCBs. Fitted with a shunt trip release (STL) for remote tripping, plus phase failure detection. No undervoltage release, no ground-fault monitoring, no communication function — this is a straightforward motor-protection breaker for a standalone feeder.
Breaking capacity reaches 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V — the 690 V figure is low enough that this breaker should not be the sole protection on a 690 V bus without selectivity study. Maximum power loss is 10 W. Operating temperature range -25 °C to 70 °C, storage -40 °C to 80 °C. Trip indicator not present; voltage trigger is available.
