Mounts in a standard panel or enclosure with a 105 mm width and 86 mm depth, leaving room for cable routing behind.
Thermal derating and endurance
Above that, the continuous current derates stepwise: 60.6375 A at 55 °C, 58.275 A at 60 °C, 55.9125 A at 65 °C, and 53.55 A at 70 °C. If the panel runs hot — near a transformer or in a crowded cabinet — the actual load must stay under the derated curve, not the nameplate 63 A. The mechanical endurance is rated at 20,000 cycles, which is standard for a distribution MCCB; not a motor-starting duty class.
