Breaking capacity is the headline: 242 kA at 240 VAC, 187 kA at 415 VAC and 440 VAC, 121 kA at 500 VAC, and 9 kA at 690 VAC. The breaker is 3-pole, rated for a minimum 600 A frame (the 3VA2 frame carries up to 4800 A maximum), so this is the 400 A trip unit in a frame that has headroom for selectivity coordination downstream.
If remote trip or ground-fault protection is needed, you'd add an external module or specify a different variant.
