The 3-pole design handles three-phase line protection, and the adjustable thermal-magnetic trip can be set between 95 A and 756 A (the full-scale value is 63 A, so the 95–756 A range likely refers to the magnetic short-circuit pickup). The 187 kA breaking capacity at 240 V drops to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 3.7 kA at 690 V — the SCCR headroom shrinks fast above 500 V, so verify the available fault current at your system voltage before committing the BOM line.
The 3-pole footprint is compact enough for multi-breaker lineups in a distribution board.
