Its interrupting capacity reaches 242 kA at 240 V and 187 kA at 415 V, which means it can clear high-fault currents in a main distribution board without upstream fuses needing to open — a key selectivity consideration for the site electrical engineer. The auxiliary switch complement is 2 auxiliary switches plus 1 trip alarm and 1 electrical alarm switch (HQ type), giving the controls integrator enough dry contacts for remote status and fault annunciation.
The continuous current rating is 630 A at 40 °C ambient, but the panel OEM must account for derating: at 50 °C it drops to 570 A, at 60 °C to 510 A, and at 70 °C to 450 A. Physical dimensions are 248 mm high, 138 mm wide, 110 mm deep. That 138 mm width is standard for a 630 A frame in the SENTRON 3VA2 family, so it will occupy one 138 mm-wide slot in a Siemens-type distribution panel. The depth of 110 mm leaves clearance for rear-connected busbars or cable ducts.
