S&C TripSaver™ Dropout Recloser for Overhead Distribution Systems.

S&C introduces TripSaver™ Dropout Recloser, a unique new product for protecting overhead lateral circuits. Used in lieu of fuse cutouts, it improves system reliability by eliminating the permanent outages caused when lateral fuses respond to temporary faults. This new device makes “fuse-saving” schemes a thing of the past.

This self-powered, electronically controlled vacuum recloser, offered in system voltage class ratings of 15.5 and 27 kV, is available for installation in new or existing cutout mountings. A two-insulator branch-feeder style mounting is also available for new installations. TripSaver requires no programming or batteries for back-up control power.

TripSaver features an open-close-open-dropout operating sequence with a 5-second reclosing time interval. The interrupter resets five seconds after dropout, ready for the next operation. The first opening operation is very fast — 1.5- to 2-cycle — total clearing time. The second opening operation has a delayed time-current characteristic equivalent to either a 50K or 100K fuse link. TripSaver’s operating sequence provides excellent coordination with upstream substation breakers and downstream transformer fuses.
