Overview
The S&C Positrol 64100 is a 100-ampere universal-style fuse link engineered for reliable protection in distribution cutout systems. Rated for standard speed operation, this 23-inch fuse link is designed to interrupt faults precisely when needed, eliminating nuisance operations that increase maintenance and downtime costs. Positrol Fuse Links operate only when a fault occurs within the cutout’s zone of protection, reducing maintenance and operation costs.
