It's a 3-pole unit rated 16 A continuously at ambient temperatures from 40 °C through 55 °C, with a slight derating to 15 A at 60-70 °C. That means it holds its full rating across the typical panel interior temperature range — no need to oversize for a warm enclosure. Breaking capacity is 52.5 kA at 240 V, 32 kA at 415 V, and still 7.5 kA at 690 V. For a 16 A frame, that's serious fault-clearing headroom — it'll ride through a high-fault scenario without upstream coordination headaches. Rated insulation voltage is 800 V, so it's comfortable on 400/480 V systems and can handle 690 V industrial supplies where the fault current stays under 7.5 kA.
That gives you status feedback and remote trip capability without adding external relay logic. Power loss is 10.6 W max at rated load. That's modest enough that you don't need special ventilation in a standard IP54 enclosure, but if you're packing multiple breakers in a small box, add it to your thermal budget.
