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.
Customer Satisfaction
Mitigate momentary and sustained outages despite the weather to improve SAIDI, SAIFI, and MAIFI.
O&M Cost Savings
Avoid unnecessary truck rolls to allow crews to focus on modernization initiatives and restoration services.
Eco-Friendly Benefits
Lower your carbon footprint with fewer trips, and replace fuses that can cause sparks and debris.
Rapid Installation and Results
Easily integrate devices into your system using cutouts and programmable fuse curves.
