Littlefuse 的 JLLS 系列保險絲分別有非電鍍和鍍銀端接兩種。
電鍍保險絲和非電鍍保險絲之間的主要區別在於鍍銀，這有助於防止腐蝕。從電氣角度來看，它們的功能相同，但添加鍍銀可增加其在腐蝕環境中的耐用性。
選擇任何保險絲時，主要考慮因素包括：
-
保險絲尺寸：對最大運轉（穩定狀態）電流施加安全係數，以確保保險絲能夠處理潛在的突波。
例如，將最大運轉電流乘以 1.25倍可得到適當的保險絲額定值。 （四捨五入至最接近的標準保險絲尺寸）
當選擇保險絲時，您還應考慮系統的其他部分，例如斷路器。斷路器製造商需要對此提供指導，因為他們要對保險絲進行協調測試。 -
用於馬達保護的延時保險絲：馬達系統，尤其是像液壓馬達這種電感較高的馬達系統，需要延時保險絲來處理啟動突波。
由於感應負載突波電流，快速熔斷器可能會過早熔斷。
選擇保險絲不僅涉及匹配電氣額定值。應考慮系統電感、斷路器協調和馬達保護。而延時保險絲最適合電感負載。
