Its interrupting capacity is specified per voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — these are the values that govern fault-clearing capability at the installed system voltage. The thermal derating curve is documented from 40 °C through 70 °C: the breaker carries the full 160 A up to 50 °C, then steps down to 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. Panel ambient temperature determines the actual continuous rating.
The integrated auxiliary trip is order code 3VA9608-0BB24. The undervoltage release is present as standard.
The 76.2 mm width corresponds to a 4-module DIN-rail footprint (18 mm per module), which governs spacing in the distribution board. This is a straightforward line-protection device for fixed-trip applications.
The trip indicator is present. No ground-fault monitoring version is fitted.
