Four poles handle three-phase plus neutral, and the interrupting capacity hits 330 kA at 240 V, 242 kA at 415 V, and still holds 187 kA at 500 V. That kind of short-circuit rating means it can sit on high-fault panels without cascading upstream breakers — a real advantage in industrial switchboards where available fault current is stiff.
Width of 140 mm means it occupies three 45 mm module spaces on a DIN rail, typical for a 4-pole MCCB in this class.
