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.
