Have you ever had a distribution-fuse cutout operate unnecessarily or for an unknown cause?
The outages caused by such operations affect your maintenance and operations costs. This, in turn, affects your fuse-link costs, making a $5 fuse link in reality a $13 fuse link or even higher. Learn more about the cost of unnecessary fuse-link operations here.
The key to eliminating this impact is to remove the unnecessary cutout operations by using reliable fuse links that act only when required.
Positrol® Fuse Links are designed to provide reliable protection, and they operate only when a fault occurs within the cutout’s zone of protection. With Positrol Fuse Links, you eliminate unnecessary cutout operations and thereby reduce your maintenance and operation costs.
