Breaking Capacity and Derating
Breaking capacity drops with system voltage: 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4.5 kA at 690 V. That 690 V figure is the weak point — if your line side runs 690 V, this breaker is not your first choice for high-fault locations. Thermal derating is published per 5 °C steps above 50 °C: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, 213 A at 70 °C.
Auxiliaries and Releases
The shunt trip allows remote tripping via a control signal — useful for emergency-stop circuits or supervisory shutdown. If you need those, you're looking at a different suffix.
Maximum power loss 48 W at rated current — factor that into enclosure ventilation if you're packing multiple breakers in a small cabinet.
