Rated 25 A at 40 °C with a TM210 thermal-magnetic overcurrent release, it clears faults up to 121 kA at 240 V AC and 75.6 kA at 415 V.
The interrupting ratings drop as voltage rises: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That 11.9 kA at 690 V is the limiting figure for a 480 V or 600 V class panel — if your available fault current exceeds that, this breaker won't hold.
Rated current holds flat at 25 A from 40 °C to 50 °C (–), then steps down to 24 A at 55 °C and 60 °C, and 23 A at 65 °C and 70 °C. In a sealed enclosure with no forced airflow, expect to derate to 23 A if ambient hits 65 °C.
