At 8A rated current and 10kA breaking capacity at 400V, this breaker safely interrupts short-circuit faults up to 10,000A without welding contacts or cascading failure upstream. The 2-pole configuration switches both phase conductors simultaneously, which matters for single-phase branch circuits where you need full isolation on both poles.
