Applications
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 uses a very fast 1.5 to 3.5 cycle-clearing time. The second opening operation uses a time-current characteristic equivalent to either a “K” Speed or “T” Speed fuse curve. This operating sequence provides excellent coordination with the substation breaker and downstream transformer fuses.
Unlike other single-phase reclosers, TripSaver requires no routine maintenance, field programming, or batteries for back-up power.
