UMF 250 (Au) -> Fuse with gold-plated caps, Approval Status: VDE Mark, cURus and PSE JET 

UMC 250 -> Clip, Approval Status: VDE UG Mark and cURus 

UMK 250 = UMF 250 (Au) + UMC 250 

There is no approval existing for the combination fuse and clip UMK 250, but the fuse and the clip are fully approved independently at VDE/UL. See details above. 

In the reflow soldering process, the fuse must have gold-plated caps, otherwise fuse and clip would be soldered together. For fuse replacement in the field, a standard UMF 250 fuse with tin-plated caps can be used. 

It is not allowed to replace higher rated current than 4 A in the clip.
