The continuous current derates in a predictable curve as ambient temperature 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 — so if the breaker sits in a warm enclosure, the actual load it can carry drops by roughly 2–3 % per 5 °C step above 40 °C. The interrupting capacity is what decides whether this breaker clears a fault without failing: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V. The adjustable thermal-magnetic trip range spans 945 A minimum to 5 670 A maximum, giving selectivity headroom downstream.
The base switch is order code 3VA2463-7HL32-0AA0; the -0AH0 suffix adds a factory-fitted rotary handle and extended terminal shields. Maximum power loss is 162 W — account for that heat in the enclosure thermal calculation, especially when derating for ambient temperature.
