The breaker carries a 187 kA interrupting capacity at 240 V AC, which drops to 121 kA at 415 V and 52.5 kA at 690 V — the SCCR headroom a site electrical engineer needs to verify selectivity with downstream devices.
The 800 A rating holds through 50 °C ambient. Above that, it derates linearly: 780 A at 55 °C, 761 A at 60 °C, 741 A at 65 °C, and 722 A at 70 °C. For a panel OEM packing breakers into a confined enclosure, that derating curve determines whether the 800 A frame is still the right choice or whether you step up to the next frame size.

Physical footprint
Dimensions are 320 mm high, 210 mm wide, and 120 mm deep. The 210 mm width fits standard MCCB panel cutouts for a 3-pole frame at this rating. Verify the gland-plate opening and bus-bar spacing before committing the panel layout.
