The Siemens 3VA2463-5HL32-0BA0 is a 3-pole SENTRON molded case circuit breaker rated 630 A continuous at 40 °C, sized for line protection in main or feeder distribution panels. That 630 A figure is the thermal rating in open air at 40 °C ambient; the breaker derates to 520 A at 70 °C, so if your enclosure runs hot, the real continuous capacity drops — size the upstream bus and downstream load accordingly. The interrupting capacity follows the system voltage: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V (–). If you need remote status or earth-leakage detection, this is not the version; look at the 3VA2 family with the optional shunt trip or GF add-on.
Dimensions are 110 mm deep, 138 mm wide, 248 mm high (–). The 138 mm width is standard for a 3-pole MCCB in this frame size; it occupies three 45 mm pole spaces on the DIN rail or mounting plate. Verify the gland plate cutout and door cutout against the panel layout before wiring.
