Rated 32 A continuously at 40 °C (derates to 30 A at 70 °C), it's sized for feeder or branch circuits up to that current in 50/60 Hz systems. Breaking capacity is the headline: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
That covers most indoor industrial panels; if the breaker lives in an unheated enclosure in a northern climate, the -25 °C minimum is the line you don't cross for reliable trip performance.
