Breaking capacity reaches 75.6 kA at 240 V AC, stepping down to 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V — enough headroom for most industrial fault-current scenarios on a 240 V or 400 V line.
Current rating holds at 80 A from 40 °C through 50 °C, then derates to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. Dimensions are 130 mm height, 76.2 mm width, and 70 mm depth — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling. Maximum power loss is 19.2 W, so ventilation in a sealed cabinet is advisable if several breakers are ganged.
