SCCR and selectivity
At 415 V the interrupting capacity is 154 kA, dropping to 121 kA at 440 V, and 17 kA at 500 V and 690 V. That spread means the breaker stays coordinated downstream of a transformer with a 480 V secondary — the high 240 V rating is what you'd use for the main on a 208Y/120 panel.
Rated 32 A from 40 °C through 50 °C, then 31 A at 55 °C and 60 °C, and 30 A at 65 °C and 70 °C. That's a shallow derating curve — you lose only 2 A over the full 30 °C rise — so it holds its rating well in a warm enclosure. The case is 70 mm deep, 76.2 mm wide, 130 mm tall, which fits the standard 3-pole MCCB footprint on DIN rail or a panel-mount base. Front protection is IP40, meaning no gasket needed for a dry indoor panel.
