The ATFM designation indicates the trip unit includes a thermal memory function for motor-starting duty. At 70 kA Icu @ 415 V, this breaker sits in the high-interrupting tier of the 3VA1 family — suitable for main or tie positions where fault current exceeds 50 kA. The class H rating (Ics typically 100% Icu for this series) means it can be reclosed after a fault at full rating without derating, which matters for critical process feeders where a blown fuse or welded contacts mean extended downtime. ## Panel integration The 4-pole footprint occupies standard 630 A frame space; verify panel cutout and busbar spacing against the 3VA1 mounting template before laying out the gland plate.","metaTitle":"Siemens 3VA1450-6EE42-0AA0 IEC Frame 630 Breaker, 70kA @ 415","metaDescription":"Siemens 3VA1450-6EE42-0AA0 circuit breaker, IEC frame 630, breaking capacity class H Icu=70kA @ 415V, 4-pole, In=500A.
