That's a standard fixed-trip curve for general distribution; you don't get the flexibility of an electronic trip, but you also don't need a separate power supply for the trip unit. The interrupting ratings are the headline: 220 kA at 240 V AC, 154 kA at 415 V AC, 121 kA at 440 V AC, and 17 kA at 500 V and 690 V AC. At 690 V the 17 kA rating is still respectable for a 32 A frame, but if your system runs at 480 V or 600 V class, the 121 kA at 440 V gives you a good reference point for coordination studies.
The 32 A rating holds flat from 40 °C to 50 °C, then derates to 31 A at 55 °C and 60 °C, and 30 A at 65 °C and 70 °C. That's a shallow derating curve — only 2 A lost over a 30 °C rise — which means the breaker runs cool and you don't have to oversize the frame for a warm enclosure. The power loss is 10.6 W maximum, so heat dissipation inside the panel is manageable even with several breakers ganged together. Physical dimensions: 76.2 mm wide (3 in), 130 mm tall (5.12 in), 70 mm deep (2.76 in).
