Line protection MCCB with high interrupting capacity
The interrupting capacity reaches 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V — enough to handle high-fault utility feeds without cascading upstream. No communication module, phase-failure detection, or ground-fault monitoring is built in — this is a straightforward line-protection device, not a power-monitoring breaker. The auxiliary trip is ordered separately as 3VA9608-0BB24.
Above that, derating is gradual: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration. No trip indicator is fitted, so visual status relies on the auxiliary switches or handle position.
