A new lateral protection strategy using S&C's TripSaver II Cutout-Mounted Recloser can dramatically improve the way your utility responds to 80% of faults.
When a fault occurs, this Smart Grid solution eliminates momentary outages for customers on the main feeder by only blinking the affected laterals.
This approach saves money for the utility and its customers while improving reliability for all.

① For 50-Hz applications, specify Microprocessor Control for Application on 50-Hz systems, catalog number suffic "-F".
② Minimum trip current is 5 amperes for 40 A continuous, 5 amperes for 100 A continuous and 10 amperes for 200 A continuous TripSaver II reclosers.
⬤ Applicable for protection of single-phase-to-neutral circuits only in solidly-grounded-neutral (multi-grounded-neutral) 34.5-kV systems where leakage distance to ground meets user's requirement. Uses 25-kV, 150-kV BIL mounting.
