630 A MCCB with 187 kA interrupting capacity
The Siemens 3VA2463-5HL32-0AF0 is a SENTRON 3-pole molded case circuit breaker rated for line protection, carrying 630 A continuously at 40 °C and interrupting up to 187 kA at 240 V. At 415 V and 440 V it still holds 121 kA, and at 690 V it's rated 9 kA, so the SCCR headroom is there across common industrial voltages.
The continuous current rating drops as ambient rises: 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. If your panel ambient runs 50 °C, plan for 593 A continuous — not the full 630 A. Maximum power loss is 162 W, which factors into enclosure ventilation and busbar sizing. The breaker measures 110 mm deep by 138 mm wide by 248 mm tall, so it fits standard MCCB mounting footprints in switchboard or panelboard layouts.
