Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, then derates to 75.6 kA at 500 V and 9 kA at 690 V — so this breaker handles high-fault utility feeds and transformer secondaries where available short-circuit current runs heavy.
The 630 A rating holds at 40 °C ambient; step up the panel temperature and it drops predictably — 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, 520 A at 70 °C. Maximum power loss of 162 W means the enclosure needs ventilation or forced cooling if tightly packed.
Auxiliary switching and release configuration
The base switch version is 3VA2463-5HL32-0AA0, so the -0AB0 suffix adds the aux switches at the factory.
