It holds its full 40 A rating through 50 °C; above that it derates to 38.4 A at 55 °C and 36 A at 70 °C — relevant if the breaker sits in a warm enclosure near other heat sources. Breaking capacity runs 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. For a 480 V line the 415 V figure is the closest reference; the 690 V rating confirms it handles higher-voltage industrial feeds where fault current is lower. It does not carry an undervoltage release, phase-failure detection, or ground-fault monitoring — those are separate add-on options in the 3VA family. Front protection is IP40, so it suits dry indoor panel environments.
