[A²s] Order Number 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. .xx = .11Blister Tape of 100 pcs. in Plastic Bag .xx = .22Blister Tape 33 cm Reel (1000 pcs.) 30.06.2015 Packaging Unit The specifications, descriptions and illustrations indicated in this document are based on current information.
