At 415 V it still clears 121 kA, and at 690 V it holds 52.5 kA, so the breaker is sized for systems where the transformer is close and the bus is stiff.
Above that, the thermal derating curve applies: at 55 °C it is good for 960 A, at 70 °C it drops to 900 A. The 330 W maximum power loss is the heat the breaker dissipates at full rated current — that figure feeds into the enclosure thermal calculation so the panel does not cook the other components.
No lead-time number is published here, but the part is not a phase-out or special-build item, so the supply posture is routine.
Integration notes
The breaker measures 210 mm wide, 320 mm high, and 120 mm deep. Those dimensions matter for panel layout — it is a full-size 3-pole MCCB, not a compact frame, so it needs the corresponding mounting space and bus-bar clearance. The 3-pole design with line protection means it is wired for three-phase systems and trips on overcurrent or short-circuit, not on ground fault (no ground-fault monitoring version fitted). The shunt trip allows remote tripping via a control signal, which is useful for emergency-stop circuits or automated shutdown sequences.
