MOTOR CIRCUIT PROTECTION FUSE-LINKS
A motor circuit protection fuse-link has a dual basis of current rating. The lower rationg is the maximum
continuous current rating determined by the rating of the equipment in which the fuse-link is normally fitted.
The higher rating is the operational current rating determined by the time/current characteristic of the fuse-
link. The list reference incorporates both ratings seperated by the letter "M" .(egDNS20M32)
