4 Fuse benefits
Replace the existing text of bullet point h) by the following new text:
h) Compact size offers economical overcurrent protections at high short-circuit levels
Add the following new bullet point after point p):
q) Fuse-links will operate independent of the operation position of the fuse. The operation
position is usually vertical. Other positions of use are permissible. The deratings of the
manufacturers of the fuse must be observed.
5 Fuse construction and operation
5.2.1 Fuse-link
Replace the existing third paragraph of 5.2.1 by the following new text:
The fuse-element is usually made of flat silver or copper with multiple restrictions in the cross-
section. This restriction is an important feature of fuse design, normally achieved by precision
stamping.
Replace the existing first sentence of the fourth paragraph of 5.2.1 by the following new text:
M-effect (see 5.3.3) is sometimes added to the fuse-element to achieve controlled fuse
operation in the overload range.
5.3.2 Fuse operation in case of short-circuit
Replace the existing bullet points by the following new text:
• the arcing stage (t ): the arcs begin at restrictions and are then extinguished by the filler.
