The Siemens 3VA2340-0HM42-0AA0 is a 4-pole IEC molded case circuit breaker on the 400 A frame, rated for 200 kA breaking capacity at 415 V (breaking capacity class E). The ETU330 electronic trip unit gives you adjustable overload protection (Ir = 160 A to 400 A), short-circuit protection (Ii = 1.5 to 12 × In), and ground-fault protection (Ig = 0.2 to 1 × In, tg = 0.1/0.3 s). Neutral conductor protection is selectable: OFF, 50%, or 100%.
RoHS compliant since 01-10-19. Export control: AL N / ECCN 9N9999. The product family is the 3VA Molded Case Circuit Breakers up to 1600 A, IEC, so the full IEC 60947-2 type-test documentation is available from the manufacturer.
