For a panel builder, that SCCR headroom lets you place this breaker closer to the load without worrying about cascading failure. The continuous current rating (In) is 100 A, with an adjustable overload protection band (Ir) from 70 A to 100 A via the TM220 dial. The short-circuit magnetic trip (Ii) is fixed at 10 x In, so 1000 A instantaneous pickup. That 10x multiplier is typical for line-protection (cable/feeder) duty — not motor-starting, where you'd want a higher multiplier to ride through inrush.
Deployment context
Terminal connections accept lug or busbar — verify lug size against your cable cross-section at order time.
