為什麼給定零件具有兩種不同的電壓或電流額定值可能會令人困惑，特別是當這些額定值在產品頁面、發票、描述或有時部件上實際列印的內容不匹配時，這可能會引起問題：「我收到了正確的零件嗎？」
給定的零件可能有兩個或多個認可評級，每個認可評級都有自己的測試參數，這將導致各種最大推薦評級。有時產品頁面會列出 30A，但收到的產品描述可能只列出 16A。
以 Eaton 保險絲盒 BK/S-8202-1-R 為例，客戶可能會根據說明或其他一些文件假設他們正在訂購 600V / 30A 產品，但實際收到部件時，產品或說明上可能僅顯示 300V / 16A ，這兩者本身都是正確的。
實際產品具有規格書中常見的這些評級：
UL：600V 30A
CSA：300V 16A
- 需要注意的重要方面是您的專案需要滿足哪個等級才能獲得資格？
- 是否需要獲得 UL 或 CSA 認證？
技術提示：這只是一個範例，但這些不同的核准評級可以適用於各種組件，例如開關和許多其他產品。尋找事實的最佳位置是產品規格書或系列目錄。請記住，這些文件可能會進行修訂或更新，因為零件或其測試資格可能會變更。
