## **Note:** The 50 A and 60 A ratings, it may not break current consistently when overload current is less than 200%In (represented by dotted portion of this time-current curve), as maybe arc current continuously pass-through fuse under this condition. It is not recommended to use in conditions requiring overloads below 200%In ## **Soldering Parameters–Wave Soldering** |**Wave Parameter**
