The interrupting ratings tell the story: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. That kind of short-circuit capacity is sized for high-fault industrial switchgear, not a light commercial panel. The 248 mm height, 138 mm width, and 110 mm depth put it in the larger frame of the 3VA platform — expect it to need real estate on the DIN rail or mounting plate. What it does have is a shunt trip (STL) release built in, plus two auxiliary switches and one trip-alarm switch (HQ) as standard. The maximum power loss is 96 W — enough heat that you need to think about ventilation in a sealed enclosure, especially if you're derating the current above 55 °C. The continuous current holds at 400 A up to 50 °C, then steps down: 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C. That derating curve is the one that governs real-world fit in a warm panel.
The 15000 latching endurance cycles is typical for a main breaker that sees infrequent switching; it is not a switching duty device.
