各位：
      三相的電加熱管，一根功率9KW，一共5根，是380V采用三角形接法。在選用空氣開(kāi)關(guān)和漏電開(kāi)關(guān)時(shí)有爭論，有人覺(jué)得三相漏電開(kāi)關(guān)用不起，可能用上去一會(huì )就會(huì )跳閘�，F在用得100A的空氣開(kāi)關(guān)，未發(fā)現什么問(wèn)題。怕就怕萬(wàn)一加熱管燒壞后出現漏電現象，所以想更換為100A的漏電開(kāi)關(guān)。請大家發(fā)表哈意見(jiàn)，或者有用到這么大功率的說(shuō)下經(jīng)驗。謝謝大家，我會(huì )給你們加分的哦
