It carries a continuous current rating of 125 A at 40 °C, with a derating curve that holds 125 A up to 50 °C, then steps down to 114 A at 70 °C — so you don't lose headroom in a warm enclosure unless ambient pushes past 55 °C. Breaking capacity is voltage-dependent: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
Footprint is 130 mm tall, 76.2 mm wide, 70 mm deep — a 3-pole MCCB that fits standard DIN-rail or panel-mount layouts. That gives you remote tripping capability and status feedback without adding an external relay module.
