CB級(jí)：是指轉(zhuǎn)換開(kāi)關(guān)主體如符合GB14048.2、GB14048.9，這些產(chǎn)品本身具有短路、過(guò)載保護(hù)功能，因此雙電源也具有這些功能；而主體開(kāi)關(guān)符合GB14048.3，本身產(chǎn)品不具有類(lèi)似保護(hù)功能，屬于PC級(jí)；主體開(kāi)關(guān)符合GB14048.4的則屬于CC級(jí)。 R：自投自負(fù)（意思是當(dāng)常用電源出現(xiàn)異常后，雙電源會(huì)轉(zhuǎn)換至備用電源，而當(dāng)常用電源恢復(fù)后，則轉(zhuǎn)換至常用電源，反之則屬于自投不自復(fù)）。 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-32/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-63/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-100/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-125/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-160/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-200/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-250/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-320/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-400/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-500/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-630/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-800/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-32/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-63/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-100/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-125/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-160/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-200/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-250/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-320/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-400/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-500/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-630/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGA-800/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-32/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-63/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-100/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-125/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-160/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-200/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-250/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-320/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-400/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-500/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-630/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-800/3R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-32/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-63/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-100/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-125/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-160/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-200/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-250/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-320/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-400/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-500/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-630/4R 施耐德萬(wàn)高雙電源開(kāi)關(guān)WATSGB-800/4R 面向全國(guó)供應(yīng)：
