Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — the 187 kA figure at 240 V means it can safely clear a fault up to that level without upstream devices needing to trip, which is critical for high-fault panels near large transformers or utility feeds. The overcurrent release is a TM220 thermal-magnetic design, so it provides both overload (thermal) and short-circuit (magnetic) protection in one unit.
Above that, it derates: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. That derating curve matters for panel builders stuffing breakers into a warm enclosure — if your cabinet ambient sits at 60 °C, plan for 150.4 A continuous, not 160 A.
Shunt trip and auxiliary trip options
The integrated auxiliary trip uses order code 3VA9688-0BL32. The trip indicator is also absent, so you won't get a local mechanical flag showing a trip event; you'd need the panel indication or a separate auxiliary contact for that.
