VacuFuse® Self-Resetting Interrupter
Eliminate nuisance outages and unnecessary maintenance costs.
When fuses protecting overhead distribution transformers operate, 70% of the time they’re for nuisance outages where no other repair work is needed, requiring you to roll a truck unnecessarily. That equates to 70% of these maintenance costs wasted for issues that could have been altogether avoided.
VacuFuse Self-Resetting Interrupters bring fault-testing technology furthest toward the end of the grid than had previously been possible, providing you with advanced end-to-end lateral protection for the most vulnerable and difficult-to-reach locations on your system—and saving you needless maintenance expenses.
