說(shuō)起電路安全，想起了去年公司改造的一臺設備，由于接線(xiàn)人員沒(méi)注意，錯把380接入220電路中,這一下上電后,plc燒了。電源燒了。當時(shí)不在現場(chǎng)。也沒(méi)有拍圖片，我在想之前的電路人員是怎么設計的電路�；镜碾娐繁Ｗo沒(méi)有，連plc都能燒。如果在主電路中加接觸器控制。是不是更安全。能有效保護電路?，[各位大佬如何看待電路基本保護s:17]

主電路裝接觸器配合按鈕開(kāi)關(guān)/旋鈕開(kāi)關(guān)來(lái)控制設備電源通斷，有的會(huì )用負載斷路開(kāi)關(guān)直接控制主電路通斷。
你這種接錯線(xiàn)上電就燒，和有無(wú)接觸器無(wú)關(guān)
