Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — that's headroom for high-fault installations where upstream coordination matters.
Full 63 A rating holds through 50 °C ambient. At 55 °C it derates to 60.48 A, at 60 °C to 59.22 A, at 65 °C to 57.96 A, and at 70 °C to 56.7 A. That's a shallow derating curve — you don't lose much headroom in a warm enclosure.
Integrated undervoltage release — no auxiliary contacts
There are no auxiliary contacts on this version, so if you need status feedback to a PLC, plan for a separate auxiliary switch block.
