In the high-stakes world of power distribution, the difference between a reliable grid and a catastrophic failure often comes down to thermal management. For engineers and switchgear manufacturers, the phrase is more than a search query—it is a gateway to understanding how to manage heat rise, current carrying capacity, and long-term system integrity. | Ambient Temperature | Derating Factor for Al
