Approval Overview
UMT 250 -> Fuse with tin-plated caps, Approval Status: VDE, UL LISTED, cURus, Free of CCC, PSE JET, KTL
UMT 250 (Au) -> Fuse with gold-plated caps, Approval Status: VDE Mark and cURus
UMC 250 -> Clip, Approval Status: VDE UG Mark and cURus

UMZ 250 = UMT 250 (Au) + UMC 250
There is no approval existing for the combination fuse and clip UMZ 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 UMT 250 fuse with tin-plated caps can be used. This is not allowed for the 80 mA version. This must be replaced with an original UMZ with gold caps.

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