The interrupting ratings here are what separate this from a standard distribution breaker. At 240 V it clears 187 kA; at 415 V and 440 V it holds 121 kA; at 500 V it's 75.6 kA; and at 690 V it drops to 3.7 kA. The 690 V rating is low, so if your line side runs at 690 V, this isn't the breaker for that spot.
Dimensions are 181 mm high, 105 mm wide, 86 mm deep — standard 3-pole MCCB footprint for a 100 A frame. The shunt trip adds a pair of control terminals; make sure your control voltage matches the release rating (not listed here, but typical for SENTRON shunt trips is 24 V DC or 230 V AC — verify against the specific release code).
