Over the past few years, components within an electrical control panel have got smaller. This is down to the challenges imposed by clients wanting smaller enclosures to fit within much smaller spaces. With often huge amounts of terminals, wiring, circuit breakers, RCBOs and other general electrical components packed tightly into the panel, trunking up against core high-power components, quarters can be crowded. The result is in an increased ambient heat load surrounding the enclosure, due to restricted airflow and a high density of heat-producing equipment. This makes it even more important to protect these often-expensive electronic components from the excess heat, especially as, for every 10℃ rise in temperature, the reliability of electronic components reduces by 50 percent!
