Its interrupting capacity reaches 187 kA at 240 VAC, 121 kA at 415/440 VAC, 75.6 kA at 500 VAC, and 4.5 kA at 690 VAC — covering fault levels from low-voltage service entrances down to motor-control-center buswork. This matters for panel builders sizing the breaker in a warm enclosure — the 250 A nameplate holds only below 50 °C ambient.

The storage minimum matters for unheated warehouses in cold climates — the breaker can sit at -40 °C without damage. If you need to swap the auxiliary configuration in the field, that base variant is the starting point.
