It is a 3-pole unit designed specifically for starter protection, meaning it coordinates with motor contactors and overload relays to clear faults before the contactor welds shut. The breaker carries a 330 kA interrupting rating at 240 V AC, dropping to 242 kA at 415 V and 440 V, then 187 kA at 500 V, and 3.7 kA at 690 V — the steep drop at 690 V tells you this is a 690 V rated device but the arc extinction is optimized for the 400–500 V distribution levels common in industrial panels.
