NOTES TO FIGURE 2:

0. These drawings are not intended to cover the design of fuse-links, except with regard to the dimensions and the following notes.

1. The centres of the dimensions a1, a and a4 shall not deviate from the centre of a, by more than 1.5 mm.

2. The dimension a2 shall he observed within the total area b1 /2, measured from the lower edge of the blade, over a width of at

least

4 mm on both sides of the blade. Outside this area, the dimension may be less than the values indicated for a,.

3. The contact surfaces may be plane or provided with ribs.

4. Maximum dimensions of the enclosure of the fuse-link. Within these limits, the fuse-links may be of any form, for example,

square, rectangular. circular, oval, polygonal. etc.
