We are discussing here the second structure of the PTC heating element, PTC heating element structure please refer to the explanation of its definition. How is the creepage distance of the functional insulation at the location of the red circle in Figure 1 determined? We all know that NOTE 1 of TABLE 18 section has…
distancia de fuga: distancia más corta a lo largo de la superficie del aislamiento entre dos partes conductoras o entre una parte conductora y la superficie accesible.
