Beware I have ordered this fuse twice and both times received fake fuses from China - I have original fuses to compare and they are made in Mexico so why did the package come from China? The pinch on the fuse box is incorrect and does not match the picture. Maybe they work fine - a fuse is a fuse, right? But there's a reason Fluke lists a $10 fuse for a $600 meter and I won't risk it, especially on 1000V testers.
