Interrupting capacity is the headline number here: 220 kA at 240 VAC, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. The 17 kA at 690 V still covers most industrial 690 V distribution.
Rated 160 A from 40 °C up to 50 °C, then it starts to taper: 156 A at 55 °C, 151 A at 60 °C, 147 A at 65 °C, 142 A at 70 °C. If your panel ambient runs 55 °C, you lose 4 A — not much, but worth knowing if you're loading it near the limit. Footprint: 140 mm wide, 158 mm tall, 70 mm deep. That's a standard 4-pole MCCB width — it fits the usual DIN-rail or panel-mount pattern.
Straightforward line protection for standard industrial distribution.
