  • Best-Fit: starting with the biggest exits
  • LIFO: last in-first out
  • Combifilter: Best-Fit, with more connected power of odd exits
  • Progressive: all required exits are switched in quasi one operation
»  Adjustments for every step:
  • Rated value, discharging time, regulated, on-fix, off-fix
