Fuse cutouts have an essential role in system and equipment protection on overhead distribution systems. The key determinant of a cutout’s ability to function properly is the fuse link it uses. Failure of the fuse link to perform as planned can result in miscoordination with other protective devices, nuisance operations (“sneakouts”), and needless outages. To a utility that’s dollars and cents—and not just the cost of the replacement fuse link. The expense of finding and replacing fuse links that sneak out can cost many times the up-front savings achieved through the use of less-expensive fuse links.

S&C’s Positrol Fuse Links eliminate nuisance fuse operations and, at the same time, provide reliable protection in the event of a fault within the cutout’s zone of protection. They’re manufactured in accordance with a quality system certified to ISO9001:2000.
