400 A continuous, flat across the thermal range
That flat thermal profile simplifies the BOM line: one breaker covers the feeder regardless of where it lands in the enclosure. Interrupting capacity hits 330 kA at 240 V, dropping to 242 kA at 415 V and 440 V, then 187 kA at 500 V, and 9 kA at 690 V.
Panel fit and auxiliary configuration
The depth of 110 mm is the dimension to watch when clearing the gland plate or backpanel; the width of 138 mm sets the DIN-rail or mounting-plate pitch. The trip indicator is present, so a quick visual scan confirms the breaker state without opening the door.
