It carries a 25 A continuous rating at 40 °C, and the thermal derating curve holds that same 25 A through 50 °C, then steps down to 24 A at 55–60 °C and 23 A at 65–70 °C — so in a warm enclosure you lose only a couple of amps. At 415 V it still handles 121 kA, at 440 V it's 75.6 kA, and at 500 V or 690 V it's 17 kA — that's a lot of SCCR margin for most industrial distribution boards.
What the breaking capacity numbers mean for coordination
At 415 V (common in European industrial systems) the 121 kA still covers most distribution boards. For a 25 A frame, these are high-end numbers; the 3VA series is designed for selective coordination with downstream MCBs.
