The Siemens 3VA2463-7HN32-0AG0 is a SENTRON molded case circuit breaker rated for 630 A continuous current at 40 °C, with a 330 kA interrupting capacity at 240 V. Rated insulation voltage Ui is 800 V, and the breaker carries a full thermal derating curve from 630 A at 40 °C down to 520 A at 70 °C — critical for panel builders who need to account for internal cabinet temperature rise without oversizing the frame.
This MCCB's interrupting capacity is voltage-dependent: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V. For a 480 V panel (common in North America) the 242 kA rating at 440 V is the closest reference; at 600 V class you'd interpolate between the 500 V and 690 V figures. This is not a parametric match to the 5SQ2370-2YA01, which has a different trip curve and frame size — the 3VA2463-7HN32-0AG0 is a higher-current, higher-interrupting-capacity part that would not drop into a panel wired for the 5SQ2370 without a full coordination study.
Trip unit and auxiliary contacts
The 1 auxiliary switch + 1 trip alarm switch (HP version) gives separate N/O and N/C contacts for status and alarm — the trip alarm closes only when the breaker trips on fault, not on manual open, which is useful for differentiating between a maintenance disconnect and a protective trip.
