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. **Packaging Unit** .xx = .11 acc.
