Rated 32 A at 40 °C ambient, it derates to 31.2 A at 50 °C and 30.37 A at 55 °C — the thermal curve is published, so you can size the breaker to the actual panel ambient without guessing. The interrupting capacity is 30 kA per IEC 60947-2 (400 V AC), which covers most industrial distribution boards fed by a transformer of 630 kVA or less; the DC rating is 15 kA at 72 V, useful for control-circuit or battery-backed loads. For UL 489 / UL 1077 installations the SCCR is 5 kA at 277/480 V — confirm the available fault current at the panelboard before specifying.
The breaker carries IEC 60947-2 (30 kA) and UL 1077 / CSA C22.2 No.235 (5 kA) approvals — accepted in North American and IEC markets.
