The breaking capacity drops as system voltage climbs: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 4.5 kA at 690 V. That's a high-interrupting rating at the lower voltages, suited for high-fault-current industrial panels where you need selectivity without cascading upstream.
Thermal derating — the real-world current you can carry
Above that, it steps down: 156 A at 55 °C, 151 A at 60 °C, 147 A at 65 °C, and 142 A at 70 °C. The maximum power loss is 33 W, which matters for heat buildup inside a sealed cabinet.
Integrated auxiliary and shunt trip — what's inside the case
That means you get remote status feedback and remote tripping capability without adding external modules. The shunt trip lets a PLC or safety relay kill power on demand, which is standard for emergency-stop chains on conveyor or pump starters.
