160 A MCCB with ETU560 — the so-what for your panel
At 240 V it interrupts 187 kA; at 415 V and 440 V it holds 121 kA, which covers most industrial distribution panels without needing a current-limiting upstream device. The 105 mm width and 181 mm height are standard 3VA frame dimensions, so it lands on the same mounting footprint as other 3VA breakers in this frame class.
Temperature derating — don't guess, use the curve
Above that it derates linearly: 154 A at 55 °C, 148 A at 60 °C, 142 A at 65 °C, 136 A at 70 °C. The maximum power loss is 28 W, which is modest for a 160 A frame but still needs to be factored into the enclosure thermal budget.
What's built into this variant
It has a communication function on board — useful for remote monitoring or integration into a higher-level energy management system. There is no auxiliary contact block fitted (the auxiliary contact version is listed as "Without"), and no voltage trigger or phase failure detection.
