Order Number
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.
