It is rated to interrupt faults up to 220 kA at 240 V AC, 154 kA at 415 V, and still holds 17 kA at 690 V, so it handles high available fault current on distribution transformers or large motor branch circuits without cascading upstream.
Thermal derating and ambient reality
At 55 °C it drops to 78 A, at 65 °C to 75 A, and at 70 °C to 74 A. If the panel sits near a kiln or preheater, plan for that 6 A loss at the top end.
Panel footprint and integration
The breaker measures 76.2 mm wide, 130 mm tall, 70 mm deep — a standard 3-pole MCCB footprint that drops onto a DIN rail or mounts directly. The 70 mm depth leaves room for rear bus connections in a typical 200 mm deep enclosure.
