It carries 800 A continuously at 40 °C ambient — the full rating holds through 50 °C, then derates to 722 A at 70 °C. That 800 A frame makes it a fit for large feeders, busway taps, or high-current distribution in industrial switchboards. Breaking capacity is the headline: 187 kA at 240 V AC, 121 kA at 415/440 V, 75.6 kA at 500 V, and 52.5 kA at 690 V. Those numbers put it in the high-interrupting category — it handles fault currents from large transformers or utility feeds without needing upstream current-limiting fuses.
Dimensions are 320 mm high, 210 mm wide, 120 mm deep — a standard MCCB footprint for a 3-pole 800 A frame. The auxiliary switch configuration (2 aux + 1 trip alarm) is built in, so no add-on modules are needed for remote status feedback.
