It carries a 25 A continuous rating at 40 °C, holds that rating steady through 50 °C, then derates by 1 A per 5 °C step up to 23 A at 70 °C. That thermal curve means you size the breaker for the load at the panel ambient, not the nameplate ampacity. Three poles, rated insulation voltage 800 V. The interrupting ratings climb with system voltage: 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. The overcurrent release is a TM210 — thermal-magnetic, fixed thermal, fixed magnetic. This is a straightforward thermal-magnetic breaker for basic feeder or branch protection where you don't need adjustable pickup or remote status.
Shunt trip and auxiliary release
That means you can remotely trip the breaker by energizing the shunt coil, which is useful for emergency-stop circuits or interlocking with a fire-alarm system. The undervoltage release is not fitted on this order code. If you need undervoltage protection, you'd spec a different 3VA1 suffix.
