It's a 3-pole unit rated 32 A continuously at 40 °C, and the thermal curve holds that rating flat through 50 °C before it starts a gentle derating — 31 A at 55 °C, 30 A at 70 °C. That means you can load it near nameplate in a warm enclosure without recalculating. That's a serious fault-current rating for a 32 A frame — it'll interrupt a bolted fault on a large transformer secondary without the arc flashing over to the bus. At 240 V it's even higher at 187 kA, and it still holds 17 kA at 690 V. That's enough for remote status on a PLC input and a separate alarm for trip events.
Panel fit and footprint
The 76.2 mm width is three 25.4 mm pole pitches, so busbar spacing lines up with standard 3-phase risers. Power loss is 13.1 W maximum at rated load. That's modest for a 32 A MCCB — you won't need forced ventilation in a typical panel, but it's worth summing across multiple breakers in a dense enclosure to check internal temperature rise against the derating curve.
