Breaking capacity sits at 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V.
The 160 A rating is stable at 40 °C, 45 °C, 50 °C, 55 °C, 60 °C, 65 °C, and 70 °C — no reduction as ambient rises. That simplifies panel thermal budgeting: if your load draws 160 A, this breaker holds it regardless of enclosure heat buildup up to 70 °C. The auxiliary release is a shunt trip (STL), allowing remote tripping via a control signal — useful for emergency-stop circuits or interlocking with upstream safety relays.
Maximum power loss is 19.7 W. In a sealed panel with multiple breakers, that heat adds up — account for it in the enclosure's thermal dissipation calculation to avoid exceeding the 70 °C operating maximum.
