That 160 A holds steady up to 50 °C; above that it derates 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. For a panel running warm, the 50 °C plateau is the practical sizing limit — you lose headroom fast past that. At 240 V it interrupts 75.6 kA; at 415 V that drops to 52.5 kA; at 440 V it is 32 kA; at 690 V it is 10.5 kA. The 240 V figure is the one that matters for most North American 277/480 V wye panels (line-to-neutral), while the 415 V rating governs IEC 50 Hz installations. Three-pole, line protection version. A shunt trip (STL) is integrated, with the auxiliary trip order code 3VA9688-0BL32 listed for reference if you need a replacement coil.
That is a compact 3-pole MCCB footprint — it drops into a standard SENTRON 3VA panel mount without needing a wider bucket.
