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)
