Breaking capacity is the headline number here: 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The thermal derating curve is gentle — still 63 A at 50 °C, 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C — meaning you don't lose much capacity in a warm enclosure.
Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard 3-pole MCCB footprint that fits most Siemens SENTRON mounting bases and panel cutouts. The width is exactly 3 inches, so it aligns with typical DIN-rail or backplate drilling patterns for North American panels. It ships with 2 auxiliary switches HP (high-performance) pre-installed, so you have status feedback for the PLC or SCADA without adding a separate accessory.
