What sets this breaker apart is its interrupting capacity: 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. That's a lot of fault-current muscle for a 25 A frame — it'll ride through a high-capacity transformer secondary or a large motor-control center without needing upstream current-limiting fuses.
The IP40 front face means it's fine inside a deadfront panel; just don't hose it down on the route.
The depth is 86 mm (3.39 in), with a width of 105 mm (4.13 in) and height of 181 mm (7.13 in).
