Current-carrying capacity derates with ambient temperature inside the enclosure: 630 A at 40 °C, 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C (–). The 162 W maximum power loss must be vented; mounting in a sealed IP40 front panel with 110 mm depth, 184 mm width, 248 mm height (–) leaves room for side-by-side ganging but requires a thermal calculation for the enclosure size.
