The headline breaking capacity at 240 V is 187 kA, which drops to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 17 kA at 690 V — so the interrupting capability is heavily voltage-dependent. Phase failure detection is included, which matters for motor protection on unbalanced supplies.
Thermal derating and continuous current
Above that, derating is gradual: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. Maximum power loss is 75 W, which contributes to enclosure heating.
Panel integration
The 2 auxiliary switches (HQ type) are built in, so you get status feedback without adding external contact blocks. The shunt trip (STL) is factory-fitted — it's a voltage-trigger release that lets a remote signal (e.g., from an E-stop or PLC) trip the breaker. No undervoltage release is present; if you need UVR, this variant doesn't carry it.
