The Siemens SENTRON 3VA2220-7MQ32-0BL0 is a 3-pole molded case circuit breaker (MCCB) designed specifically for motor protection, carrying a continuous current rating of 200 A across its full ambient temperature range from 40 °C to 70 °C — meaning no derating is needed for typical panel environments up to 70 °C ambient. Its interrupting capacity hits 330 kA at 240 V, 242 kA at 415 V, and 187 kA at 500 V, but drops to 5.2 kA at 690 V; that high-end 690 V figure tells you this breaker is sized for 400 V class systems where fault current is the constraint, not a 690 V line where the available fault current is low.
Motor protection features and panel integration
This MCCB includes phase failure detection and an undervoltage release, tripping on a lost phase or sag below dropout threshold. The integrated communication function enables remote monitoring. A trip indicator is present. Maximum power loss is 46 W.
