It carries an ETU310M electronic trip unit with an adjustable overcurrent release range from 300 A to 1500 A, making it suitable for motor branch circuits where the breaker must coordinate with a contactor and overload relay. Breaking capacity is 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 steep drop at 690 V reflects the design limit of the 800 V rated insulation voltage. Power loss is 10 W maximum at rated current — negligible for enclosure thermal budgeting but worth noting for dense multi-breaker layouts.
Compliance documentation: the SENTRON 3VA series carries IEC 60947-2 certification for molded case circuit breakers. RoHS and REACH declarations are standard from Siemens for current-production parts. UL listing is typical for the 3VA family, though the specific UL file number is not carried in this listing; confirm with the order desk if UL marking is required for the panel build.
