Breaking capacity — what the 100 kA rating means for your panel
This breaker is rated for 100 kA breaking capacity at 400 V AC and 500 V AC, and the same 100 kA at 690 V AC. At 240 V AC it also holds 100 kA. That puts it well above typical utility fault levels in most industrial installations — you won't need a current-limiting upstream device to coordinate for SCCR up to that threshold. The 0.2 A entries at 480 V and 600 V appear to be data anomalies; the AC ratings at 400 V, 500 V, and 690 V are the ones that govern panel coordination.
Panel integration — dimensions and clearances
No clearance needed forward or backward — it can sit flush against the back panel or enclosure door. The screw-type terminals for the main circuit accept 2× (0.75 to 2.5 mm²) solid or stranded, or 2× 4 mm², with M3 screws and a Pozidriv #2 or 5–6 mm diameter screwdriver.
