ABSTRACT:
A fuse element is a ribbon of aluminum or aluminum alloy having a terminal at each end of the ribbon. Each terminal is made of copper sheet material having a portion that is tin plated. The tin plated portion is folded over the end of the ribbon to contact both sides and is welded to the ribbon to form a connection capable of carrying short circuit currents and able to withstand repeated temperature changes. Preferably the weld consists of three side-by-side spot welds extending on either side of the ribbon to the respective tin plated terminal portion.
