Up to 80% of faults on overhead lateral lines are caused by temporary issues, such as vegetation, animals, and storms.
S&C’s TripSaver II recloser replaces fuses and automatically restores power after temporary faults, preventing outages and unnecessary truck rolls.
Avoid disturbances that disrupt your customers and impact your bottom line with S&C’s single-phase recloser.
Single-Phase Reclosers vs. Fuses
Lateral fusing strategies force trade-offs. Customers either experience a sustained or momentary interruption. Crews must be sent to replace the blown fuse and restore power. See how S&C’s single-phase recloser combines the best of fuse-saving and fuse-blowing strategies in one device to mitigate or isolate outages closer to the fault.
Advantages
Win massive gains by advancing your lateral protection strategy with TripSaver II reclosers.
