Above that, derate linearly: 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, 45 A at 70 °C. Maximum power dissipation at rated load is 4.87 W — negligible for enclosure heat budgeting but worth noting if ganged with other breakers in a sealed box.
DIN-rail mount, 25.4 mm wide (1 inch) — one standard module width. Depth 70 mm, height 130 mm. IP40 front protection (finger-safe behind the panel door, not rated for washdown). Neutral conductor not field-upgradeable.
