What this MCCB is and what the ratings mean
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. The 200 A full-scale rating with a 40 A initial setting range (adjustable) lets you dial in the overload protection for the connected motor's FLA without swapping the breaker body.
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. Auxiliary switch configuration: 2 auxiliary switches + 1 trip alarm switch + 1 electrical alarm switch HQ. Dimensions: 86 mm deep, 105 mm wide, 181 mm tall. Maximum power loss is 46 W.
